+
+ * Dimensions from look up table.
+ 
+
+ 
+
+ * Dimensions from look up table with hierarchy.
+

+
+1. Run ${KYLIN_HOME}/bin/sample.sh ; Restart kylin server to flush the caches;
+2. Logon Kylin web, select project "learn_kylin";
+3. Select the sample cube "kylin_sales_cube", click "Actions" -> "Build", pick up a date later than 2014-01-01 (to cover all 10000 sample records);
+4. Check the build progress in "Jobs" tab, until 100%;
+5. Execute SQLs in the "Query" tab, for example:
+ select part_dt, sum(price) as total_selled, count(distinct seller_id) as sellers from kylin_sales group by part_dt order by part_dt
+6. You can verify the query result and compare the response time with hive;
+
+
+## What's next

+permalink: /docs2/tutorial/powerbi.html
+version: v1.2
+since: v1.2
+---
+
+Microsoft Excel is one of the most famous data tool on Windows platform, and has plenty of data analyzing functions. With Power Query installed as plug-in, excel can easily read data from ODBC data source and fill spreadsheets.
+
+Microsoft Power BI is a business intelligence tool providing rich functionality and experience for data visualization and processing to user.
+
+> Apache Kylin currently doesn't support query on raw data yet, some queries might fail and cause some exceptions in application. Patch KYLIN-1075 is recommended to get better look of query result.
+
+> Power BI and Excel do not support "connect live" model for other ODBC driver yet, please pay attention when you query on huge dataset, it may pull too many data into your client which will take a while even fail at the end.
+
+### Install ODBC Driver
+Refer to this guide: [Kylin ODBC Driver Tutorial](./odbc.html).
+Please make sure to download and install Kylin ODBC Driver __v1.2__. If you already installed ODBC Driver in your system, please uninstall it first.
+
+### Kylin and Excel
+1. Download Power Query from Microsoft’s Website and install it. Then run Excel, switch to `Power Query` fast tab, click `From Other Sources` dropdown list, and select `ODBC` item.
+
+
+2. You’ll see `From ODBC` dialog, just type Database Connection String of Apache Kylin Server in the `Connection String` textbox. Optionally you can type a SQL statement in `SQL statement` textbox. Click `OK`, result set will run to your spreadsheet now.
+
+
+> Tips: In order to simplify the Database Connection String, DSN is recommended, which can shorten the Connection String like `DSN=[YOUR_DSN_NAME]`. Details about DSN, refer to [https://support.microsoft.com/en-us/kb/305599](https://support.microsoft.com/en-us/kb/305599).
+
+3. If you didn’t input the SQL statement in last step, Power Query will list all tables in the project, which means you can load data from the whole table. But, since Apache Kylin cannot query on raw data currently, this function may be limited.
+
+
+4. Hold on for a while, the data is lying in Excel now.
+
+
+5. If you want to sync data with Kylin Server, just right click the data source in right panel, and select `Refresh`, then you’ll see the latest data.
+
+6. To improve data loading performance, you can enable `Fast data load` in Power Query, but this will make your UI unresponsive for a while.
+
+### Power BI
+1. Run Power BI Desktop, and click `Get Data` button, then select `ODBC` as data source type.
+
+
+2. Same with Excel, just type Database Connection String of Apache Kylin Server in the `Connection String` textbox, and optionally type a SQL statement in `SQL statement` textbox. Click `OK`, the result set will come to Power BI as a new data source query.
+
+
+3. If you didn’t input the SQL statement in last step, Power BI will list all tables in the project, which means you can load data from the whole table. But, since Apache Kylin cannot query on raw data currently, this function may be limited.
+
+
+4. Now you can start to enjoy analyzing with Power BI.
+
+
+5. To reload the data and redraw the charts, just click `Refresh` button in `Home` fast tab.

+> There are some limitations of Kylin ODBC driver with Tableau, please read carefully this instruction before you try it.
+>
+> * Only support "managed" analysis path, Kylin engine will raise exception for unexpected dimension or metric
+> * Please always select Fact Table first, then add lookup tables with correct join condition (defined join type in cube)
+> * Do not try to join between fact tables or lookup tables;
+> * You can try to use high cardinality dimensions like seller id as Tableau Filter, but the engine will only return limited seller id in Tableau's filter now.
+
+### For Tableau 9.x User
+Please refer to [Tableau 9.x Tutorial](./tableau_91.html) for detail guide.
+
+### Step 1. Install Kylin ODBC Driver
+Refer to this guide: [Kylin ODBC Driver Tutorial](./odbc.html).
+
+### Step 2. Connect to Kylin Server
+> We recommended to use Connect Using Driver instead of Using DSN.
+
+Connect Using Driver: Select "Other Database(ODBC)" in the left panel and choose KylinODBCDriver in the pop-up window.
+
+
+
+Enter your Sever location and credentials: server host, port, username and password.
+
+
+
+Click "Connect" to get the list of projects that you have permission to access. See details about permission in [Kylin Cube Permission Grant Tutorial](./acl.html). Then choose the project you want to connect in the drop down list.
+
+
+
+Click "Done" to complete the connection.
+
+
+
+### Step 3. Using Single Table or Multiple Tables
+> Limitation
+>
+> * Must select FACT table first
+> * Do not support select from lookup table only
+> * The join condition must match within cube definition
+
+**Select Fact Table**
+
+Select `Multiple Tables`.
+
+
+
+Then click `Add Table...` to add a fact table.
+
+
+
+
+
+**Select Look-up Table**
+
+Click `Add Table...` to add a look-up table.
+
+
+
+Set up the join clause carefully.
+
+
+
+Keep add tables through click `Add Table...` until all the look-up tables have been added properly. Give the connection a name for use in Tableau.
+
+
+
+**Using Connect Live**
+
+There are three types of `Data Connection`. Choose the `Connect Live` option.
+
+
+
+Then you can enjoy analyzing with Tableau.
+
+
+
+**Add additional look-up Tables**
+
+Click `Data` in the top menu bar, select `Edit Tables...` to update the look-up table information.
+
+
+
+### Step 4. Using Customized SQL
+To use customized SQL resembles using Single Table/Multiple Tables, except that you just need to paste your SQL in `Custom SQL` tab and take the same instruction as above.
+
+
+
+### Step 5. Publish to Tableau Server
+Suppose you have finished making a dashboard with Tableau, you can publish it to Tableau Server.
+Click `Server` in the top menu bar, select `Publish Workbook...`.
+
+
+
+Then sign in your Tableau Server and prepare to publish.
+
+
+
+If you're Using Driver Connect instead of DSN connect, you'll need to additionally embed your password in. Click the `Authentication` button at left bottom and select `Embedded Password`. Click `Publish` and you will see the result.
+
+
+
+### Tips
+* Hide Table name in Tableau
+
+ * Tableau will display columns be grouped by source table name, but user may want to organize columns with different structure. Using "Group by Folder" in Tableau and Create Folders to group different columns.

+## 2. Available Hive Tables in Kylin
+Although Kylin will using SQL as query interface and leverage Hive metadata, kylin will not enable user to query all hive tables since it's a pre-build OLAP (MOLAP) system so far. To enable Table in Kylin, it will be easy to using "Sync" function to sync up tables from Hive.
+
+
+
+## 3. Kylin OLAP Cube
+Kylin's OLAP Cubes are pre-calculation datasets from Star Schema Hive tables, Here's the web management interface for user to explorer, manage all cubes.Go to `Cubes` Menu, it will list all cubes available in system:

+
+ 
+
+* Access (Grant user/role privileges, Grant operation only open to Admin in beta):
+
+ 
+
+## 4. Write and Execute SQL on web
+Kylin's web offer a simple query tool for user to run SQL to explorer existing cube, verify result and explorer the result set using #5's Pivot analysis and visualization
+
+> **Query Limit**
+>
+> 1. Only SELECT query be supported
+>
+> 2. To avoid huge network traffic from server to client, the scan range's threshold be set to 1,000,000 in beta.

+version: v1.2
+since: v1.2
+---
+
+Here are some basic technical concepts used in Apache Kylin, please check them for your reference.
+For terminology in domain, please refer to: [Terminology](terminology.md)
+
+## CUBE
+* __Table__ - This is definition of hive tables as source of cubes, which must be synced before building cubes.
+
+
+* __Data Model__ - This describes a [STAR SCHEMA](https://en.wikipedia.org/wiki/Star_schema) data model, which defines fact/lookup tables and filter condition.
+
+
+* __Cube Descriptor__ - This describes definition and settings for a cube instance, defining which data model to use, what dimensions and measures to have, how to partition to segments and how to handle auto-merge etc.
+
+
+* __Cube Instance__ - This is instance of cube, built from one cube descriptor, and consist of one or more cube segments according partition settings.
+
+
+* __Partition__ - User can define a DATE/STRING column as partition column on cube descriptor, to separate one cube into several segments with different date periods.
+
+
+* __Cube Segment__ - This is actual carrier of cube data, and maps to a HTable in HBase. One building job creates one new segment for the cube instance. Once data change on specified data period, we can refresh related segments to avoid rebuilding whole cube.
+
+
+* __Aggregation Group__ - Each aggregation group is subset of dimensions, and build cuboid with combinations inside. It aims at pruning for optimization.
+
+
+## DIMENSION & MEASURE
+* __Mandotary__ - This dimension type is used for cuboid pruning, if a dimension is specified as “mandatory”, then those combinations without such dimension are pruned.
+* __Hierarchy__ - This dimension type is used for cuboid pruning, if dimension A,B,C forms a “hierarchy” relation, then only combinations with A, AB or ABC shall be remained.
+* __Derived__ - On lookup tables, some dimensions could be generated from its PK, so there's specific mapping between them and FK from fact table. So those dimensions are DERIVED and don't participate in cuboid generation.
+
+
+* __Count Distinct(HyperLogLog)__ - Immediate COUNT DISTINCT is hard to calculate, a approximate algorithm - [HyperLogLog](https://en.wikipedia.org/wiki/HyperLogLog) is introduced, and keep error rate in a lower level.
+* __Count Distinct(Precise)__ - Precise COUNT DISTINCT will be pre-calculated basing on RoaringBitmap, currently only int or bigint are supported.
+* __Top N__ - (Will release in 2.x) For example, with this measure type, user can easily get specified numbers of top sellers/buyers etc.
+
+
+## CUBE ACTIONS
+* __BUILD__ - Given an interval of partition column, this action is to build a new cube segment.
+* __REFRESH__ - This action will rebuilt cube segment in some partition period, which is used in case of source table increasing.
+* __MERGE__ - This action will merge multiple continuous cube segments into single one. This can be automated with auto-merge settings in cube descriptor.
+* __PURGE__ - Clear segments under a cube instance. This will only update metadata, and won't delete cube data from HBase.
+
+
+## JOB STATUS
+* __NEW__ - This denotes one job has been just created.
+* __PENDING__ - This denotes one job is paused by job scheduler and waiting for resources.
+* __RUNNING__ - This denotes one job is running in progress.
+* __FINISHED__ - This denotes one job is successfully finished.
+* __ERROR__ - This denotes one job is aborted with errors.
+* __DISCARDED__ - This denotes one job is cancelled by end users.
+
+
+## JOB ACTION
+* __RESUME__ - Once a job in ERROR status, this action will try to restore it from latest successful point.
+* __DISCARD__ - No matter status of a job is, user can end it and release resources with DISCARD action.

+### Some NPM error causes ERROR exit (中国大陆地区用户请特别注意此问题)?
+For people from China:
+
+* Please add proxy for your NPM (请为NPM设置代理):
+`npm config set proxy http://YOUR_PROXY_IP`
+
+* Please update your local NPM repository to using any mirror of npmjs.org, like Taobao NPM (请更新您本地的NPM仓库以使用国内的NPM镜像，例如淘宝NPM镜像) :
+[http://npm.taobao.org](http://npm.taobao.org)
+
+### Can't get master address from ZooKeeper" when installing Kylin on Hortonworks Sandbox
+Check out [https://github.com/KylinOLAP/Kylin/issues/9](https://github.com/KylinOLAP/Kylin/issues/9).
+
+### Map Reduce Job information can't display on sandbox deployment
+Check out [https://github.com/KylinOLAP/Kylin/issues/40](https://github.com/KylinOLAP/Kylin/issues/40)
+
+#### Install Kylin on CDH 5.2 or Hadoop 2.5.x
+Check out discussion: [https://groups.google.com/forum/?utm_medium=email&utm_source=footer#!msg/kylin-olap/X0GZfsX1jLc/nzs6xAhNpLkJ](https://groups.google.com/forum/?utm_medium=email&utm_source=footer#!msg/kylin-olap/X0GZfsX1jLc/nzs6xAhNpLkJ)
+{% highlight Groff markup %}
+I was able to deploy Kylin with following option in POM.
+<hadoop2.version>2.5.0</hadoop2.version>
+<yarn.version>2.5.0</yarn.version>
+<hbase-hadoop2.version>0.98.6-hadoop2</hbase-hadoop2.version>
+<zookeeper.version>3.4.5</zookeeper.version>
+<hive.version>0.13.1</hive.version>
+My Cluster is running on Cloudera Distribution CDH 5.2.0.
+{% endhighlight %}
+
+#### Unable to load a big cube as HTable, with java.lang.OutOfMemoryError: unable to create new native thread
+HBase (as of writing) allocates one thread per region when bulk loading a HTable. Try reduce the number of regions of your cube by setting its "capacity" to "MEDIUM" or "LARGE". Also tweaks OS & JVM can allow more threads, for example see [this article](http://blog.egilh.com/2006/06/2811aspx.html).
+
+#### Failed to run BuildCubeWithEngineTest, saying failed to connect to hbase while hbase is active
+User may get this error when first time run hbase client, please check the error trace to see whether there is an error saying couldn't access a folder like "/hadoop/hbase/local/jars"; If that folder doesn't exist, create it.
+
+#### SUM(field) returns a negtive result while all the numbers in this field are > 0
+If a column is declared as integer in Hive, the SQL engine (calcite) will use column's type (integer) as the data type for "SUM(field)", while the aggregated value on this field may exceed the scope of integer; in that case the cast will cause a negtive value be returned; The workround is, alter that column's type to BIGINT in hive, and then sync the table schema to Kylin (the cube doesn't need rebuild); Keep in mind that, always declare as BIGINT in hive for an integer column which would be used as a measure in Kylin; See hive number types: [https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Types#LanguageManualTypes-NumericTypes](https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Types#LanguageManualTypes-NumericTypes)
+
+#### Why Kylin need extract the distinct columns from Fact Table before building cube?
+Kylin uses dictionary to encode the values in each column, this greatly reduce the cube's storage size. To build the dictionary, Kylin need fetch the distinct values for each column.
+
+#### Why Kylin calculate the HIVE table cardinality?
+The cardinality of dimensions is an important measure of cube complexity. The higher the cardinality, the bigger the cube, and thus the longer to build and the slower to query. Cardinality > 1,000 is worth attention and > 1,000,000 should be avoided at best effort. For optimal cube performance, try reduce high cardinality by categorize values or derive features.
+
+#### How to add new user or change the default password?
+Kylin web's security is implemented with Spring security framework, where the kylinSecurity.xml is the main configuration file:
+{% highlight Groff markup %}
+${KYLIN_HOME}/tomcat/webapps/kylin/WEB-INF/classes/kylinSecurity.xml
+{% endhighlight %}
+The password hash for pre-defined test users can be found in the profile "sandbox,testing" part; To change the default password, you need generate a new hash and then update it here, please refer to the code snippet in: [https://stackoverflow.com/questions/25844419/spring-bcryptpasswordencoder-generate-different-password-for-same-input](https://stackoverflow.com/questions/25844419/spring-bcryptpasswordencoder-generate-different-password-for-same-input)
+When you deploy Kylin for more users, switch to LDAP authentication is recommended; To enable LDAP authentication, update "kylin.sandbox" in conf/kylin.properties to false, and also configure the ldap.* properties in ${KYLIN_HOME}/conf/kylin.properties
+
+#### Using sub-query for un-supported SQL
+
+{% highlight Groff markup %}
+Original SQL:
+select fact.slr_sgmt,
+sum(case when cal.RTL_WEEK_BEG_DT = '2015-09-06' then gmv else 0 end) as W36,
+sum(case when cal.RTL_WEEK_BEG_DT = '2015-08-30' then gmv else 0 end) as W35

+Here are some domain terms we are using in Apache Kylin, please check them for your reference.
+They are basic knowledge of Apache Kylin which also will help to well understand such concerpt, term, knowledge, theory and others about Data Warehouse, Business Intelligence for analycits.
+
+* __Data Warehouse__: a data warehouse (DW or DWH), also known as an enterprise data warehouse (EDW), is a system used for reporting and data analysis, [wikipedia](https://en.wikipedia.org/wiki/Data_warehouse)
+* __Business Intelligence__: Business intelligence (BI) is the set of techniques and tools for the transformation of raw data into meaningful and useful information for business analysis purposes, [wikipedia](https://en.wikipedia.org/wiki/Business_intelligence)

+title: How to Clean/Backup HBase Tables
+categories: howto
+permalink: /docs2/howto/howto_backup_hbase.html
+version: v1.0
+since: v0.7.1
+---
+
+Kylin persists all data (meta data and cube) in HBase; You may want to export the data sometimes for whatever purposes
+(backup, migration, troubleshotting etc); This page describes the steps to do this and also there is a Java app for you to do this easily.
+
+Steps:
+
+1. Cleanup unused cubes to save storage space (be cautious on production!): run the following command in hbase CLI:
+{% highlight Groff markup %}
+hbase org.apache.hadoop.util.RunJar /${KYLIN_HOME}/lib/kylin-job-(version).jar org.apache.kylin.job.hadoop.cube.StorageCleanupJob --delete true
+{% endhighlight %}
+2. List all HBase tables, iterate and then export each Kylin table to HDFS;
+See [https://hbase.apache.org/book/ops_mgt.html#export](https://hbase.apache.org/book/ops_mgt.html#export)
+
+3. Copy the export folder from HDFS to local file system, and then archive it;
+
+4. (optional) Download the archive from Hadoop CLI to local;
+
+5. Cleanup the export folder from CLI HDFS and local file system;
+
+Kylin provide the "ExportHBaseData.java" (currently only exist in "minicluster" branch) for you to do the
+step 2-5 in one run; Please ensure the correct path of "kylin.properties" has been set in the sys env; This Java uses the sandbox config by default;

+title: How to Backup Metadata
+categories: howto
+permalink: /docs2/howto/howto_backup_metadata.html
+version: v1.0
+since: v0.7.1
+---
+
+Kylin organizes all of its metadata (including cube descriptions and instances, projects, inverted index description and instances, jobs, tables and dictionaries) as a hierarchy file system. However, Kylin uses hbase to store it, rather than normal file system. If you check your kylin configuration file(kylin.properties) you will find such a line:
+
+{% highlight Groff markup %}
+## The metadata store in hbase
+kylin.metadata.url=kylin_metadata@hbase
+{% endhighlight %}
+
+This indicates that the metadata will be saved as a htable called `kylin_metadata`. You can scan the htable in hbase shell to check it out.
+
+## Backup Metadata Store with binary package
+
+Sometimes you need to backup the Kylin's Metadata Store from hbase to your disk file system.
+In such cases, assuming you're on the hadoop CLI(or sandbox) where you deployed Kylin, you can go to KYLIN_HOME and run :
+
+{% highlight Groff markup %}
+./bin/metastore.sh backup
+{% endhighlight %}
+
+to dump your metadata to your local folder a folder under KYLIN_HOME/metadata_backps, the folder is named after current time with the syntax: KYLIN_HOME/meta_backups/meta_year_month_day_hour_minute_second
+
+## Restore Metadata Store with binary package
+
+In case you find your metadata store messed up, and you want to restore to a previous backup:
+
+Firstly, reset the metadata store (this will clean everything of the Kylin metadata store in hbase, make sure to backup):
+
+{% highlight Groff markup %}
+./bin/metastore.sh reset
+{% endhighlight %}
+
+Then upload the backup metadata to Kylin's metadata store:
+{% highlight Groff markup %}
+./bin/metastore.sh restore $KYLIN_HOME/meta_backups/meta_xxxx_xx_xx_xx_xx_xx
+{% endhighlight %}
+
+## Backup/restore metadata in development env (available since 0.7.3)
+
+When developing/debugging Kylin, typically you have a dev machine with an IDE, and a backend sandbox. Usually you'll write code and run test cases at dev machine. It would be troublesome if you always have to put a binary package in the sandbox to check the metadata. There is a helper class called SandboxMetastoreCLI to help you download/upload metadata locally at your dev machine. Follow the Usage information and run it in your IDE.
+
+## Cleanup unused resources from Metadata Store (available since 0.7.3)
+As time goes on, some resources like dictionary, table snapshots became useless (as the cube segment be dropped or merged), but they still take space there; You can run command to find and cleanup them from metadata store:
+
+Firstly, run a check, this is safe as it will not change anything:
+{% highlight Groff markup %}
+./bin/metastore.sh clean
+{% endhighlight %}
+
+The resources that will be dropped will be listed;
+
+Next, add the "--delete true" parameter to cleanup those resources; before this, make sure you have made a backup of the metadata store;
+{% highlight Groff markup %}
+./bin/metastore.sh clean --delete true
+{% endhighlight %}

+{% endhighlight %}
+
+### 2. Get details of cube.
+* `GET http://localhost:7070/kylin/api/cubes?cubeName={cube_name}&limit=15&offset=0`
+* Client can find cube segment date ranges in returned cube detail.
+{% highlight Groff markup %}

+version: v0.7.2

+---
+
+Kylin will generate intermediate files in HDFS during the cube building; Besides, when purge/drop/merge cubes, some HBase tables may be left in HBase and will no longer be queried; Although Kylin has started to do some
+automated garbage collection, it might not cover all cases; You can do an offline storage cleanup periodically:
+
+Steps:
+1. Check which resources can be cleanup, this will not remove anything:
+{% highlight Groff markup %}
+hbase org.apache.hadoop.util.RunJar ${KYLIN_HOME}/lib/kylin-job-(version).jar org.apache.kylin.job.hadoop.cube.StorageCleanupJob --delete false
+{% endhighlight %}
+Here please replace (version) with the specific Kylin jar version in your installation;
+2. You can pickup 1 or 2 resources to check whether they're no longer be referred; Then add the "--delete true" option to start the cleanup:
+{% highlight Groff markup %}
+hbase org.apache.hadoop.util.RunJar ${KYLIN_HOME}/lib/kylin-job-(version).jar org.apache.kylin.job.hadoop.cube.StorageCleanupJob --delete true
+{% endhighlight %}
+On finish, the intermediate HDFS location and HTables will be dropped;

+categories: howto
+permalink: /docs2/howto/howto_ldap_and_sso.html
+version: v2.0
+since: v1.0
+---
+
+## Enable LDAP authentication
+
+Kylin supports LDAP authentication for enterprise or production deployment; This is implemented with Spring Security framework; Before enable LDAP, please contact your LDAP administrator to get necessary information, like LDAP server URL, username/password, search patterns;
+
+#### Configure LDAP server info
+
+Firstly, provide LDAP URL, and username/password if the LDAP server is secured; The password in kylin.properties need be salted; You can Google "Generate a BCrypt Password" or run org.apache.kylin.rest.security.PasswordPlaceholderConfigurer to get a hash of your password.
+
+```
+ldap.server=ldap://<your_ldap_host>:<port>
+ldap.username=<your_user_name>
+ldap.password=<your_password_hash>
+```
+
+Secondly, provide the user search patterns, this is by LDAP design, here is just a sample:
+
+```
+ldap.user.searchBase=OU=UserAccounts,DC=mycompany,DC=com
+ldap.user.searchPattern=(&(AccountName={0})(memberOf=CN=MYCOMPANY-USERS,DC=mycompany,DC=com))
+ldap.user.groupSearchBase=OU=Group,DC=mycompany,DC=com
+```
+
+If you have service accounts (e.g, for system integration) which also need be authenticated, configure them in ldap.service.*; Otherwise, leave them be empty;
+
+### Configure the administrator group and default role
+
+To map an LDAP group to the admin group in Kylin, need set the "acl.adminRole" to "ROLE_" + GROUP_NAME. For example, in LDAP the group "KYLIN-ADMIN-GROUP" is the list of administrators, here need set it as:
+
+```
+acl.adminRole=ROLE_KYLIN-ADMIN-GROUP
+acl.defaultRole=ROLE_ANALYST,ROLE_MODELER
+```
+
+The "acl.defaultRole" is a list of the default roles that grant to everyone, keep it as-is.
+
+#### Enable LDAP
+
+For Kylin v0.x and v1.x: set "kylin.sandbox=false" in conf/kylin.properties, then restart Kylin server;
+For Kylin since v2.0: set "kylin.security.profile=ldap" in conf/kylin.properties, then restart Kylin server;
+
+## Enable SSO authentication
+
+From v2.0, Kylin provides SSO with SAML. The implementation is based on Spring Security SAML Extension. You can read [this reference](http://docs.spring.io/autorepo/docs/spring-security-saml/1.0.x-SNAPSHOT/reference/htmlsingle/) to get an overall understand.
+
+Before trying this, you should have successfully enabled LDAP and managed users with it, as SSO server may only do authentication, Kylin need search LDAP to get the user's detail information.
+
+### Generate IDP metadata xml
+Contact your IDP (ID provider), asking to generate the SSO metadata file; Usually you need provide three piece of info:
+
+ 1. Partner entity ID, which is an unique ID of your app, e.g,: https://host-name/kylin/saml/metadata
+ 2. App callback endpoint, to which the SAML assertion be posted, it need be: https://host-name/kylin/saml/SSO
+ 3. Public certificate of Kylin server, the SSO server will encrypt the message with it.
+
+### Generate JKS keystore for Kylin
+As Kylin need send encrypted message (signed with Kylin's private key) to SSO server, a keystore (JKS) need be provided. There are a couple ways to generate the keystore, below is a sample.
+
+Assume kylin.crt is the public certificate file, kylin.key is the private certificate file; firstly create a PKCS#12 file with openssl, then convert it to JKS with keytool:
+
+```
+$ openssl pkcs12 -export -in kylin.crt -inkey kylin.key -out kylin.p12
+Enter Export Password: <export_pwd>
+Verifying - Enter Export Password: <export_pwd>
+
+
+$ keytool -importkeystore -srckeystore kylin.p12 -srcstoretype PKCS12 -srcstorepass <export_pwd> -alias 1 -destkeystore samlKeystore.jks -destalias kylin -destkeypass changeit
+
+Enter destination keystore password: changeit
+Re-enter new password: changeit
+```
+
+It will put the keys to "samlKeystore.jks" with alias "kylin";
+
+### Enable Higher Ciphers
+
+Make sure your environment is ready to handle higher level crypto keys, you may need to download Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files, copy local_policy.jar and US_export_policy.jar to $JAVA_HOME/jre/lib/security .
+
+### Deploy IDP xml file and keystore to Kylin
+
+The IDP metadata and keystore file need be deployed in Kylin web app's classpath in $KYLIN_HOME/tomcat/webapps/kylin/WEB-INF/classes
+
+ 1. Name the IDP file to sso_metadata.xml and then copy to Kylin's classpath;
+ 2. Name the keystore as "samlKeystore.jks" and then copy to Kylin's classpath;
+ 3. If you use another alias or password, remember to update that kylinSecurity.xml accordingly:
+
+```
+<!-- Central storage of cryptographic keys -->
+<bean id="keyManager" class="org.springframework.security.saml.key.JKSKeyManager">
+ <constructor-arg value="classpath:samlKeystore.jks"/>
+ <constructor-arg type="java.lang.String" value="changeit"/>
+ <constructor-arg>
+ <map>
+ <entry key="kylin" value="changeit"/>
+ </map>
+ </constructor-arg>
+ <constructor-arg type="java.lang.String" value="kylin"/>
+</bean>
+
+```
+
+### Other configurations
+In conf/kylin.properties, add the following properties with your server information:
+
+```
+saml.metadata.entityBaseURL=https://host-name/kylin
+saml.context.scheme=https
+saml.context.serverName=host-name
+saml.context.serverPort=443
+saml.context.contextPath=/kylin
+```
+
+Please note, Kylin assume in the SAML message there is a "email" attribute representing the login user, and the name before @ will be used to search LDAP.
+
+### Enable SSO
+Set "kylin.security.profile=saml" in conf/kylin.properties, then restart Kylin server; After that, type a URL like "/kylin" or "/kylin/cubes" will redirect to SSO for login, and jump back after be authorized. While login with LDAP is still available, you can type "/kylin/login" to use original way. The Rest API (/kylin/api/*) still use LDAP + basic authentication, no impact.

+## Hierarchies:
+
+Theoretically for N dimensions you'll end up with 2^N dimension combinations. However for some group of dimensions there are no need to create so many combinations. For example, if you have three dimensions: continent, country, city (In hierarchies, the "bigger" dimension comes first). You will only need the following three combinations of group by when you do drill down analysis:
+
+group by continent
+group by continent, country
+group by continent, country, city
+
+In such cases the combination count is reduced from 2^3=8 to 3, which is a great optimization. The same goes for the YEAR,QUATER,MONTH,DATE case.
+
+If we Donate the hierarchy dimension as H1,H2,H3, typical scenarios would be:
+
+
+A. Hierarchies on lookup table
+
+
+<table>
+ <tr>
+ <td align="center">Fact table</td>
+ <td align="center">(joins)</td>
+ <td align="center">Lookup Table</td>
+ </tr>
+ <tr>
+ <td>column1,column2,,,,,, FK</td>
+ <td></td>
+ <td>PK,,H1,H2,H3,,,,</td>
+ </tr>
+</table>
+
+---
+
+B. Hierarchies on fact table
+
+
+<table>
+ <tr>
+ <td align="center">Fact table</td>
+ </tr>
+ <tr>
+ <td>column1,column2,,,H1,H2,H3,,,,,,, </td>
+ </tr>
+</table>
+
+---
+
+
+There is a special case for scenario A, where PK on the lookup table is accidentally being part of the hierarchies. For example we have a calendar lookup table where cal_dt is the primary key:
+
+A*. Hierarchies on lookup table over its primary key
+
+
+<table>
+ <tr>
+ <td align="center">Lookup Table(Calendar)</td>
+ </tr>
+ <tr>
+ <td>cal_dt(PK), week_beg_dt, month_beg_dt, quarter_beg_dt,,,</td>
+ </tr>
+</table>
+
+---
+
+
+For cases like A* what you need is another optimization called "Derived Columns"
+
+## Derived Columns:
+
+Derived column is used when one or more dimensions (They must be dimension on lookup table, these columns are called "Derived") can be deduced from another(Usually it is the corresponding FK, this is called the "host column")
+
+For example, suppose we have a lookup table where we join fact table and it with "where DimA = DimX". Notice in Kylin, if you choose FK into a dimension, the corresponding PK will be automatically querable, without any extra cost. The secret is that since FK and PK are always identical, Kylin can apply filters/groupby on the FK first, and transparently replace them to PK. This indicates that if we want the DimA(FK), DimX(PK), DimB, DimC in our cube, we can safely choose DimA,DimB,DimC only.
+
+<table>
+ <tr>
+ <td align="center">Fact table</td>
+ <td align="center">(joins)</td>
+ <td align="center">Lookup Table</td>
+ </tr>
+ <tr>
+ <td>column1,column2,,,,,, DimA(FK) </td>
+ <td></td>
+ <td>DimX(PK),,DimB, DimC</td>
+ </tr>
+</table>
+
+---
+
+
+Let's say that DimA(the dimension representing FK/PK) has a special mapping to DimB:
+
+
+<table>
+ <tr>
+ <th>dimA</th>
+ <th>dimB</th>
+ <th>dimC</th>
+ </tr>
+ <tr>
+ <td>1</td>
+ <td>a</td>
+ <td>?</td>
+ </tr>
+ <tr>
+ <td>2</td>
+ <td>b</td>
+ <td>?</td>
+ </tr>
+ <tr>
+ <td>3</td>
+ <td>c</td>
+ <td>?</td>
+ </tr>
+ <tr>
+ <td>4</td>
+ <td>a</td>
+ <td>?</td>
+ </tr>
+</table>
+
+
+in this case, given a value in DimA, the value of DimB is determined, so we say dimB can be derived from DimA. When we build a cube that contains both DimA and DimB, we simple include DimA, and marking DimB as derived. Derived column(DimB) does not participant in cuboids generation:
+
+original combinations:
+ABC,AB,AC,BC,A,B,C
+
+combinations when driving B from A:
+AC,A,C
+
+at Runtime, in case queries like "select count(*) from fact_table inner join looup1 group by looup1 .dimB", it is expecting cuboid containing DimB to answer the query. However, DimB will appear in NONE of the cuboids due to derived optimization. In this case, we modify the execution plan to make it group by DimA(its host column) first, we'll get intermediate answer like:
+
+
+<table>
+ <tr>
+ <th>DimA</th>
+ <th>count(*)</th>
+ </tr>
+ <tr>
+ <td>1</td>
+ <td>1</td>
+ </tr>
+ <tr>
+ <td>2</td>
+ <td>1</td>
+ </tr>
+ <tr>
+ <td>3</td>
+ <td>1</td>
+ </tr>
+ <tr>
+ <td>4</td>
+ <td>1</td>
+ </tr>
+</table>
+
+
+Afterwards, Kylin will replace DimA values with DimB values(since both of their values are in lookup table, Kylin can load the whole lookup table into memory and build a mapping for them), and the intermediate result becomes:
+
+
+<table>
+ <tr>
+ <th>DimB</th>
+ <th>count(*)</th>
+ </tr>
+ <tr>
+ <td>a</td>
+ <td>1</td>
+ </tr>
+ <tr>
+ <td>b</td>
+ <td>1</td>
+ </tr>
+ <tr>
+ <td>c</td>
+ <td>1</td>
+ </tr>
+ <tr>
+ <td>a</td>
+ <td>1</td>
+ </tr>
+</table>
+
+
+After this, the runtime SQL engine(calcite) will further aggregate the intermediate result to:
+
+
+<table>
+ <tr>
+ <th>DimB</th>
+ <th>count(*)</th>
+ </tr>
+ <tr>
+ <td>a</td>
+ <td>2</td>
+ </tr>
+ <tr>
+ <td>b</td>
+ <td>1</td>
+ </tr>
+ <tr>
+ <td>c</td>
+ <td>1</td>
+ </tr>
+</table>
+
+
+this step happens at query runtime, this is what it means "at the cost of extra runtime aggregation"

+title: How to Upgrade
+categories: howto
+permalink: /docs2/howto/howto_upgrade.html
+version: v1.2
+since: v0.7.1
+---
+
+## Upgrade among v0.7.x and v1.x
+
+From v0.7.1 to latest v1.2, Kylin's metadata is backward compatible, the upgrade can be finished in couple of minutes:
+
+#### 1. Backup metadata
+Backup the Kylin metadata peridically is a good practice, and is highly suggested before upgrade;
+
+```
+cd $KYLIN_HOME
+./bin/metastore.sh backup
+```
+It will print the backup folder, take it down and make sure it will not be deleted before the upgrade finished. If there is no "metastore.sh", use HBase's snapshot command to do backup:
+
+```
+hbase shell
+snapshot 'kylin_metadata', 'kylin_metadata_backup20150610'
+```
+Here 'kylin_metadata' is the default kylin metadata table name, replace it with the right table name of your Kylin;
+
+#### 2. Install new Kylin and copy back "conf"
+Download the new Kylin binary package from Kylin's download page; Extract it to a different folder other than current KYLIN_HOME; Before copy back the "conf" folder, do a compare and merge between the old and new kylin.properties to ensure newly introduced property will be kept.
+
+#### 3. Stop old and start new Kylin instance
+```
+cd $KYLIN_HOME
+./bin/kylin.sh stop
+export KYLIN_HOME="<path_of_new_installation>"
+cd $KYLIN_HOME
+./bin/kylin.sh start
+```
+
+#### 4. Back-port if the upgrade is failed
+If the new version couldn't startup and need back-port, shutdown it and then switch to the old KYLIN_HOME to start. Idealy that would return to the origin state. If the metadata is broken, restore it from the backup folder.
+
+```
+./bin/metastore.sh restore <path_of_metadata_backup>
+```
+
+## Upgrade from v0.6.x to v0.7.x
+
+In v0.7, Kylin refactored the metadata structure, for the new features like inverted-index and streaming; If you have cube created with v0.6 and want to keep in v0.7, a migration is needed; (Please skip v0.7.1 as
+it has several compatible issues and the fix will be included in v0.7.2) Below is the steps;
+
+#### 1. Backup v0.6 metadata
+To avoid data loss in the migration, a backup at the very beginning is always suggested; You can use HBase's backup or snapshot command to achieve this; Here is a sample with snapshot:
+
+```
+hbase shell
+snapshot 'kylin_metadata', 'kylin_metadata_backup20150610'
+```
+
+'kylin_metadata' is the default kylin metadata table name, replace it with the right table name of your Kylin;
+
+#### 2. Dump v0.6 metadata to local file
+This is also a backup method; As the migration tool is only tested with local file system, this step is must; All metadata need be downloaded, including snapshot, dictionary, etc;
+
+```
+hbase org.apache.hadoop.util.RunJar ${KYLIN_HOME}/lib/kylin-job-x.x.x-job.jar org.apache.kylin.common.persistence.ResourceTool download ./meta_dump
+```
+
+(./meta_dump is the local folder that the metadata will be downloaded, change to name you preferred)
+
+#### 3. Run CubeMetadataUpgrade to migrate the metadata
+This step is to run the migration tool to parse the v0.6 metadata and then convert to v0.7 format; A verification will be performed in the last, and report error if some cube couldn't be migrated;
+
+```
+hbase org.apache.hadoop.util.RunJar ${KYLIN_HOME}/lib/kylin-job-x.x.x-job.jar org.apache.kylin.job.CubeMetadataUpgrade ./meta_dump
+```
+
+1. The tool will not overwrite v0.6 metadata; It will create a new folder with "_v2" suffix in the same folder, in this case the "./meta_dump_v2" will be created;
+2. By default this tool will only migrate the job history in last 30 days; If you want to keep elder job history, please tweak upgradeJobInstance() method by your own;
+3. If you see _No error or warning messages; The migration is success_ , that's good; Otherwise please check the error/warning messages carefully;
+4. For some problem you may need manually update the JSON file, to check whether the problem is gone, you can run a verify against the new metadata:
+
+```
+hbase org.apache.hadoop.util.RunJar ${KYLIN_HOME}/lib/kylin-job-x.x.x-job.jar org.apache.kylin.job.CubeMetadataUpgrade ./meta_dump2 verify
+```
+
+#### 4. Upload the new metadata to HBase
+Now the new format of metadata will be upload to the HBase to replace the old format; Stop Kylin, and then:
+
+```
+hbase org.apache.hadoop.util.RunJar ${KYLIN_HOME}/lib/kylin-job-x.x.x-job.jar org.apache.kylin.common.persistence.ResourceTool reset
+hbase org.apache.hadoop.util.RunJar ${KYLIN_HOME}/lib/kylin-job-x.x.x-job.jar org.apache.kylin.common.persistence.ResourceTool upload ./meta_dump_v2
+```
+
+#### 5. Update HTables to use new coprocessor
+Kylin uses HBase coprocessor to do server side aggregation; When Kylin instance upgrades to V0.7, the HTables that created in V0.6 should also be updated to use the new coprocessor:
+
+```
+hbase org.apache.hadoop.util.RunJar ${KYLIN_HOME}/lib/kylin-job-x.x.x-job.jar org.apache.kylin.job.tools.DeployCoprocessorCLI ${KYLIN_HOME}/lib/kylin-coprocessor-x.x.x.jar
+```
+
+Done; Update your v0.7 Kylin configure to point to the same metadata HBase table, then start Kylin server; Check whether all cubes and other information are kept;

+Kylin security is based on basic access authorization, if you want to use API in your javascript, you need to add authorization info in http headers.
+
+## Example on Query API.
+```
+$.ajaxSetup({
+ headers: { 'Authorization': "Basic eWFu**********X***ZA==", 'Content-Type': 'application/json;charset=utf-8' } // use your own authorization code here
+ });
+ var request = $.ajax({
+ url: "http://hostname/kylin/api/query",
+ type: "POST",
+ data: '{"sql":"select count(*) from SUMMARY;","offset":0,"limit":50000,"acceptPartial":true,"project":"test"}',
+ dataType: "json"
+ });
+ request.done(function( msg ) {
+ alert(msg);
+ });
+ request.fail(function( jqXHR, textStatus ) {
+ alert( "Request failed: " + textStatus );
+ });
+
+```
+
+## Keypoints
+1. add basic access authorization info in http headers.
+2. use right ajax type and data synax.
+
+## Basic access authorization
+For what is basic access authorization, refer to [Wikipedia Page](http://en.wikipedia.org/wiki/Basic_access_authentication).
+How to generate your authorization code (download and import "jquery.base64.js" from [https://github.com/yckart/jquery.base64.js](https://github.com/yckart/jquery.base64.js)).
+
+```
+var authorizationCode = $.base64('encode', 'NT_USERNAME' + ":" + 'NT_PASSWORD');
+
+$.ajaxSetup({
+ headers: {
+ 'Authorization': "Basic " + authorizationCode,
+ 'Content-Type': 'application/json;charset=utf-8'
+ }
+});
+```

+## Enable LZO compression
+
+By default Kylin leverages snappy compression to compress the output of MR jobs, as well as hbase table storage, reducing the storage overhead. We do not choose LZO compression in Kylin because hadoop venders tend to not include LZO in their distributions due to license(GPL) issues. To enable LZO in Kylin, follow these steps:
+
+#### Make sure LZO is working in your environment
+
+We have a simple tool to test whether LZO is well installed on EVERY SERVER in hbase cluster ( http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.2.4/bk_installing_manually_book/content/ch_install_hdfs_yarn_chapter.html#install-snappy-man-install ), and restart the cluster.
+To test it on the hadoop CLI that you deployed Kylin, Just run
+
+{% highlight Groff markup %}
+hbase org.apache.hadoop.hbase.util.CompressionTest file:///PATH-TO-A-LOCAL-TMP-FILE lzo
+{% endhighlight %}
+
+If no exception is printed, you're good to go. Otherwise you'll need to first install LZO properly on this server.
+To test if the hbase cluster is ready to create LZO compressed tables, test following hbase command:
+
+{% highlight Groff markup %}
+create 'lzoTable', {NAME => 'colFam',COMPRESSION => 'LZO'}
+{% endhighlight %}
+
+#### Use LZO for HBase compression
+
+You'll need to stop Kylin first by running `./kylin.sh stop`, and then modify $KYLIN_HOME/conf/kylin_job_conf.xml by uncommenting some configuration entries related to LZO compression.
+After this, you need to run `./kylin.sh start` to start Kylin again. Now Kylin will use LZO to compress MR outputs and hbase tables.
+
+Goto $KYLIN_HOME/conf/kylin.properties, change kylin.hbase.default.compression.codec=snappy to kylin.hbase.default.compression.codec=lzo
+
+#### Use LZO for MR jobs
+
+Modify $KYLIN_HOME/conf/kylin_job_conf.xml by changing all org.apache.hadoop.io.compress.SnappyCodec to com.hadoop.compression.lzo.LzoCodec.
+
+Start Kylin again. Now Kylin will use LZO to compress MR outputs and HBase tables.
+

+
+## Hadoop Environment
+
+Kylin requires you having access to a hadoop CLI, where you have full permissions to hdfs, hive, hbase and map-reduce. To make things easier we strongly recommend you starting with running Kylin on a hadoop sandbox, like <http://hortonworks.com/products/hortonworks-sandbox/>. In the following tutorial we'll go with **Hortonworks Sandbox 2.1** and **Cloudera QuickStart VM 5.1**.
+
+To avoid permission issue, we suggest you using `root` account. The password for **Hortonworks Sandbox 2.1** is `hadoop` , for **Cloudera QuickStart VM 5.1** is `cloudera`.
+
+We also suggest you using bridged mode instead of NAT mode in your virtual box settings. Bridged mode will assign your sandbox an independent IP so that you can avoid issues like https://github.com/KylinOLAP/Kylin/issues/12
+
+### Start Hadoop
+
+Please make sure Hive, HDFS and HBase are available on our CLI machine.
+If you don't know how, here's a simple tutorial for hortonworks sanbox:
+
+Use ambari helps to launch hadoop:
+
+ambari-agent start
+ambari-server start
+
+With both command successfully run you can go to ambari homepage at <http://your_sandbox_ip:8080> (user:admin,password:admin) to check everything's status. **By default hortonworks ambari disables Hbase, you'll need manually start the `Hbase` service at ambari homepage.**
+
+
+
+**Additonal Info for setting up HortonWorks Sandbox on Virtual Box**
+
+ Please make sure Hbase Master port [Default 60000] and Zookeeper [Default 2181] is forwarded to Host OS.

+
+### Environment
+
+Kylin requires a properly setup hadoop environment to run. Following are the minimal request to run Kylin, for more detial, please check this reference: [Hadoop Environment](hadoop_env.html).
+
+## Recommended Hadoop Versions
+
+* Hadoop: 2.4 - 2.7
+* Hive: 0.13 - 0.14
+* HBase: 0.98 - 0.99
+* JDK: 1.7+
+
+_Tested with Hortonworks HDP 2.2 and Cloudera Quickstart VM 5.1_
+
+
+It is most common to install Kylin on a Hadoop client machine. It can be used for demo use, or for those who want to host their own web site to provide Kylin service. The scenario is depicted as:
+
+
+
+For normal use cases, the application in the above picture means Kylin Web, which contains a web interface for cube building, querying and all sorts of management. Kylin Web launches a query engine for querying and a cube build engine for building cubes. These two engines interact with the Hadoop components, like hive and hbase.
+
+Except for some prerequisite software installations, the core of Kylin installation is accomplished by running a single script. After running the script, you will be able to build sample cube and query the tables behind the cubes via a unified web interface.
+
+### Install Kylin
+
+1. Download latest Kylin binaries at [http://kylin.apache.org/download](http://kylin.apache.org/download)
+2. Export KYLIN_HOME pointing to the extracted Kylin folder
+3. Make sure the user has the privilege to run hadoop, hive and hbase cmd in shell. If you are not so sure, you can run **bin/check-env.sh**, it will print out the detail information if you have some environment issues.
+4. To start Kylin, simply run **bin/kylin.sh start**
+5. To stop Kylin, simply run **bin/kylin.sh stop**
+
+> If you want to have multiple Kylin nodes please refer to [this](kylin_cluster.html)
+
+After Kylin started you can visit <http://your_hostname:7070/kylin>. The username/password is ADMIN/KYLIN. It's a clean Kylin homepage with nothing in there. To start with you can:
+
+1. [Quick play with a sample cube](../tutorial/kylin_sample.html)
+2. [Create and Build your own cube](../tutorial/create_cube.html)
+3. [Kylin Web Tutorial](../tutorial/web.html)

+
+
+### Kylin Server modes
+
+Kylin instances are stateless, the runtime state is saved in its "Metadata Store" in hbase (kylin.metadata.url config in conf/kylin.properties). For load balance considerations it is possible to start multiple Kylin instances sharing the same metadata store (thus sharing the same state on table schemas, job status, cube status, etc.)
+
+Each of the kylin instances has a kylin.server.mode entry in conf/kylin.properties specifying the runtime mode, it has three options: 1. "job" for running job engine only 2. "query" for running query engine only and 3 "all" for running both. Notice that only one server can run the job engine("all" mode or "job" mode), the others must all be "query" mode.
+
+A typical scenario is depicted in the following chart:
+
+
+
+### Setting up Multiple Kylin REST servers
+
+If you are running Kylin in a cluster or you have multiple Kylin REST server instances, please make sure you have the following property correctly configured in ${KYLIN_HOME}/conf/kylin.properties
+
+1. kylin.rest.servers
+ List of web servers in use, this enables one web server instance to sync up with other servers. For example: kylin.rest.servers=sandbox1:7070,sandbox2:7070
+
+2. kylin.server.mode
+ Make sure there is only one instance whose "kylin.server.mode" is set to "all" if there are multiple instances.

+---
+
+With help of SequenceIQ, we have put together a fully automated method of creating a Kylin cluster (along with Hadoop, HBase and Hive). The only thing you will need to do is to pull the container from the official Docker repository by using the commands listed below:
+
+### Pre-Requisite
+
+1. Docker (If you don't have Docker installed, follow this [link](https://docs.docker.com/installation/#installation))
+2. Minimum RAM - 4Gb (We'll be running Kylin, Hadoop, HBase & Hive)
+
+### Installation
+{% highlight Groff markup %}
+docker pull sequenceiq/kylin:0.7.2
+{% endhighlight %}
+
+Once the container is pulled you are ready to start playing with Kylin. Get the following helper functions from our Kylin GitHub [repository](https://github.com/sequenceiq/docker-kylin/blob/master/ambari-functions) - _(make sure you source it)._
+
+{% highlight Groff markup %}
+ $ wget https://raw.githubusercontent.com/sequenceiq/docker-kylin/master/ambari-functions
+ $ source ambari-functions
+{% endhighlight %}
+{% highlight Groff markup %}
+ $ kylin-deploy-cluster 1
+{% endhighlight %}
+
+You can specify the number of nodes you'd like to have in your cluster (1 in this case). Once we installed all the necessary Hadoop
+services we'll build Kylin on top of it and then you can reach the UI on:
+{% highlight Groff markup %}
+#Ambari Dashboard
+http://<container_ip>:8080
+{% endhighlight %}
+Use `admin/admin` to login. Make sure HBase is running.
+
+{% highlight Groff markup %}
+#Kylin Dashboard
+http://<container_ip>:7070/kylin
+{% endhighlight %}
+The default credentials to login are: `ADMIN:KYLIN`.
+The cluster is pre-populated with sample data and is ready to build cubes as shown [here](../tutorial/create_cube.html).

+## INTRODUCTION
+
+In most cases our automated script [Installation Guide](index.html) can help you launch Kylin in your hadoop sandbox and even your hadoop cluster. However, in case something went wrong in the deploy script, this article comes as an reference guide to fix your issues.
+
+Basically this article explains every step in the automatic script. We assume that you are already very familiar with Hadoop operations on Linux.
+
+## PREREQUISITES
+* Tomcat installed, with CATALINA_HOME exported.
+* Kylin binary pacakge copied to local and setup $KYLIN_HOME correctly
+
+## STEPS
+
+### 4. Prepare Jars
+
+There are two jars that Kylin will need to use, there two jars and configured in the default kylin.properties:
+
+```
+kylin.job.jar=/tmp/kylin/kylin-job-latest.jar
+
+```
+
+This is job jar that Kylin uses for MR jobs. You need to copy $KYLIN_HOME/job/target/kylin-job-latest.jar to /tmp/kylin/
+
+```
+kylin.coprocessor.local.jar=/tmp/kylin/kylin-coprocessor-latest.jar
+
+```
+
+This is a hbase coprocessor jar that Kylin will put on hbase. It is used for performance boosting. You need to copy $KYLIN_HOME/storage/target/kylin-coprocessor-latest.jar to /tmp/kylin/
+
+### 5. Start Kylin
+
+Start Kylin with
+
+`./kylin.sh start`
+
+and stop Kylin with
+
+`./Kylin.sh stop`
