+
+Kylin is doing a round code refactor which will introduce the following two changes on meta data:
+
+* Abstract a "model_desc" layer from "cube_desc"
+
+Before define a cube, user will need firstly define a model ("model_desc"); The model defines which is the fact table, which are lookup tables and how they be joined;
+
+With the model be defined, when user define a cube ("cube_desc"), he/she only need to specify the table/column name for a dimension, as the join conditions have already been defined;
+
+This abstraction is to extend the meta data to fulfill non-cube queries (coming soon);
+
+* Support data tables from multiple hive databases;
+
+User has the case that tables are from multiple hive database, and the table name might be the same; To support this case Kylin will use the database name + table name as the unique name for tables; And user need to specify the database name (if it is not "default") in SQL when query Kylin.
+
+Here is a sample; the fact table "test_kylin_fact" is from default hive database, you don't need to specify the db name; while lookup table is from "edw", you need use "edw.test_cal_dt" in the query:
+
+{% highlight Groff markup %}
+select test_cal_dt.Week_Beg_Dt, sum(price) as c1, count(1) as c2
+ from test_kylin_fact
+ inner JOIN edw.test_cal_dt as test_cal_dt
+ ON test_kylin_fact.cal_dt = test_cal_dt.cal_dt
+ where test_kylin_fact.lstg_format_name='ABIN'
+{% endhighlight %}

+## Run test case with HBase Mini Cluster
+
+Kylin is moving as many as possible unit test cases from sandbox to HBase mini cluster, so that user can run tests easily in local without a hadoop sandbox; Two maven profiles are created in the root pom.xml, "default" and "sandbox"; The default profile will startup a HBase Mini Cluster to prepare the test data and run the unit tests (the test cases that are not supported by Mini cluster have been added in the "exclude" list); If you want to keep using Sandbox to run test, just run:
+mvn test -P sandbox
+
+
+### When use the "default" profile, Kylin will:
+
+* Startup a HBase minicluster and update KylinConfig with the dynamic HBase configurations;
+* Create Kylin metadata tables and import six example cube tables;
+* Import the hbase data from a tar ball from local: examples/test_case_data/minicluster/hbase-export.tar.gz (the hbase-export.tar.gz will be updated on complete of running BuildCubeWithEngineTest）
+* After all test cases be completed, shutdown minicluster and cleanup KylinConfig cache;
+
+### To ensure Mini cluster can run successfully, you need:
+* Make sure JAVA_HOME is properly set;

+
+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_qa@hbase:sandbox.hortonworks.com:2181:/hbase-unsecure
+{% endhighlight %}
+
+
+This indicates that the metadata will be saved as a htable called `kylin_metadata_qa`. You can scan the htable in hbase shell to check it out.
+
+# Backup Metadata Store
+
+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 use:
+
+{% highlight Groff markup %}
+mkdir ~/meta_dump
+
+hbase org.apache.hadoop.util.RunJar PATH_TO_KYLIN_JOB_JAR_FOLDER/kylin-job-x.x.x-SNAPSHOT-job.jar com.kylinolap.common.persistence.ResourceTool copy PATH_TO_KYLIN_CONFIG/kylin.properties ~/meta_dump
+{% endhighlight %}
+
+to dump your metadata to your local folder ~/meta_dump.
+
+# Restore Metadata Store
+
+In case you find your metadata store messed up, and you want to restore to a previous backup:
+
+first clean up the metadata store:
+
+{% highlight Groff markup %}
+hbase org.apache.hadoop.util.RunJar PATH_TO_KYLIN_JOB_JAR_FOLDER/kylin-job-x.x.x-SNAPSHOT-job.jar com.kylinolap.common.persistence.ResourceTool reset
+{% endhighlight %}
+
+then upload the backup metadata in ~/meta_dump to Kylin's metadata store:
+
+{% highlight Groff markup %}
+hbase org.apache.hadoop.util.RunJar PATH_TO_KYLIN_JOB_JAR_FOLDER/kylin-job-x.x.x-SNAPSHOT-job.jar com.kylinolap.common.persistence.ResourceTool copy ~/meta_dump PATH_TO_KYLIN_CONFIG/kylin.properties

-
-#### Some NPM error causes ERROR exit (中国大陆地区用户请特别注意此问题)?
-Check out [https://github.com/KylinOLAP/Kylin/issues/35](https://github.com/KylinOLAP/Kylin/issues/35)
-
-#### 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).
-
-#### Install scripted finished in my virtual machine, but cannot visit via http://localhost:9080
-Check out [https://github.com/KylinOLAP/Kylin/issues/12](https://github.com/KylinOLAP/Kylin/issues/12).
-
-#### 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.

+#### 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)

+<p class="content-header" style="margin-top:0.25em">What should I use Kylin for?</p>
+<p class="content-p">
+If you want to do multi-dimension analysis on large data sets (billion+ rows) with low query latency (sub-seconds), Kylin is a good option. Kylin also provides good integration with existing BI tools (e.g Tableau).
+</p>
+
+<hr/>
+
+<p class="content-header">Why existing SQL-on-Hadoop solutions fall short?</p>
+<p class="content-p">
+The existing SQL-on-Hadoop needs to scan partial or whole data set to answer a user query. Due to large data scan, many queries are very slow (minute+ latency).
+</p>
+<hr/>
+
+<p class="content-header">What is MOLAP/ROLAP?</p>
+<p class="content-p">
+MOLAP (Multi-dimensional OLAP) is to pre-compute data along different dimensions of interest and store resultant values in the cube. MOLAP is much faster but is inflexible.
+ROLAP (Relational-OLAP) is to use star or snow-flake schema to do runtime aggregation. ROLAP is flexible but much slower.
+</p>
+<hr/>
+
+<p class="content-header">How does Kylin support ROLAP/MOLAP?</p>
+<p class="content-p">
+Kylin builds data cube (MOLAP) from hive table (ROLAP) according to the metadata definition.
+If the query can be fulfilled by data cube, Kylin will route the query to data cube that is MOLAP.
+If the query can’t be fulfilled by data cube, Kylin will route the query to hive table that is ROLAP.
+Basically, you can think Kylin as HOLAP on top of MOLAP and ROLAP.
+</p>
+<hr/>
+<p class="content-header">What does a Kylin query look like?</p>
+<p class="content-p">
+Kylin supports join, projection, filter, aggregation, groups and sub-query. For example:
+<div align="left">
+
+<pre class="prettyprint" style="margin-top:1em;">select test_cal_dt.week_beg_dt, test_category.lv1_categ, test_category.lv2_categ, test_kylin_fact.format_name, test_sites.site_name, sum(test_kylin_fact.price) as total_price, count(*) as total_count from test_kylin_fact left join test_cal_dt on test_kylin_fact.cal_dt = test_cal_dt.cal_dt left join test_category on test_kylin_fact.leaf_categ_id = test_category.leaf_categ_id and test_kylin_fact.site_id = test_category.site_id left join test_sites on test_kylin_fact.site_id = test_sites.site_id where test_kylin_fact.seller_id = 123456 or test_kylin_fact.format_name = 'New' group by test_cal_dt.week_beg_dt, test_category.lv1_categ, test_category.lv2_categ, test_kylin_fact.format_name, test_sites.site_name</pre>
+</div>
+<hr/>
+
+<p class="content-header">What Hadoop components does it work with?</p>
+<p class="content-p">
+Kylin depends on HDFS, MapReduce, Hive and HBase.
+Hive and MapReduce is used for cube building. Hive is used for pre-join and MapReduce is used for pre-aggregation.
+HDFS is used to store intermediated files during cube building.
+HBase is used to store data cube and answer the query. HBase coprocessor is also used for query processing.

-Kylin is doing a round code refactor which will introduce the following two changes on meta data:
-
-* Abstract a "model_desc" layer from "cube_desc"
-
-Before define a cube, user will need firstly define a model ("model_desc"); The model defines which is the fact table, which are lookup tables and how they be joined;
-
-With the model be defined, when user define a cube ("cube_desc"), he/she only need to specify the table/column name for a dimension, as the join conditions have already been defined;
-
-This abstraction is to extend the meta data to fulfill non-cube queries (coming soon);
-
-* Support data tables from multiple hive databases;
-
-User has the case that tables are from multiple hive database, and the table name might be the same; To support this case Kylin will use the database name + table name as the unique name for tables; And user need to specify the database name (if it is not "default") in SQL when query Kylin.
-
-Here is a sample; the fact table "test_kylin_fact" is from default hive database, you don't need to specify the db name; while lookup table is from "edw", you need use "edw.test_cal_dt" in the query:
-
-{% highlight Groff markup %}
-select test_cal_dt.Week_Beg_Dt, sum(price) as c1, count(1) as c2
- from test_kylin_fact
- inner JOIN edw.test_cal_dt as test_cal_dt
- ON test_kylin_fact.cal_dt = test_cal_dt.cal_dt
- where test_kylin_fact.lstg_format_name='ABIN'

-## Run test case with HBase Mini Cluster
-
-Kylin is moving as many as possible unit test cases from sandbox to HBase mini cluster, so that user can run tests easily in local without a hadoop sandbox; Two maven profiles are created in the root pom.xml, "default" and "sandbox"; The default profile will startup a HBase Mini Cluster to prepare the test data and run the unit tests (the test cases that are not supported by Mini cluster have been added in the "exclude" list); If you want to keep using Sandbox to run test, just run:
-mvn test -P sandbox
-
-
-### When use the "default" profile, Kylin will:
-
-* Startup a HBase minicluster and update KylinConfig with the dynamic HBase configurations;
-* Create Kylin metadata tables and import six example cube tables;
-* Import the hbase data from a tar ball from local: examples/test_case_data/minicluster/hbase-export.tar.gz (the hbase-export.tar.gz will be updated on complete of running BuildCubeWithEngineTest）
-* After all test cases be completed, shutdown minicluster and cleanup KylinConfig cache;
-
-### To ensure Mini cluster can run successfully, you need:
-* Make sure JAVA_HOME is properly set;

-
-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_qa@hbase:sandbox.hortonworks.com:2181:/hbase-unsecure
-{% endhighlight %}
-
-
-This indicates that the metadata will be saved as a htable called `kylin_metadata_qa`. You can scan the htable in hbase shell to check it out.
-
-# Backup Metadata Store
-
-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 use:
-
-{% highlight Groff markup %}
-mkdir ~/meta_dump
-
-hbase org.apache.hadoop.util.RunJar PATH_TO_KYLIN_JOB_JAR_FOLDER/kylin-job-x.x.x-SNAPSHOT-job.jar com.kylinolap.common.persistence.ResourceTool copy PATH_TO_KYLIN_CONFIG/kylin.properties ~/meta_dump
-{% endhighlight %}
-
-to dump your metadata to your local folder ~/meta_dump.
-
-# Restore Metadata Store
-
-In case you find your metadata store messed up, and you want to restore to a previous backup:
-
-first clean up the metadata store:
-
-{% highlight Groff markup %}
-hbase org.apache.hadoop.util.RunJar PATH_TO_KYLIN_JOB_JAR_FOLDER/kylin-job-x.x.x-SNAPSHOT-job.jar com.kylinolap.common.persistence.ResourceTool reset
-{% endhighlight %}
-
-then upload the backup metadata in ~/meta_dump to Kylin's metadata store:
-
-{% highlight Groff markup %}
-hbase org.apache.hadoop.util.RunJar PATH_TO_KYLIN_JOB_JAR_FOLDER/kylin-job-x.x.x-SNAPSHOT-job.jar com.kylinolap.common.persistence.ResourceTool copy ~/meta_dump PATH_TO_KYLIN_CONFIG/kylin.properties

-<p class="content-p">
-MOLAP (Multi-dimensional OLAP) is to pre-compute data along different dimensions of interest and store resultant values in the cube. MOLAP is much faster but is inflexible.

-<p class="content-header">What Hadoop components does it work with?</p>
-<p class="content-p">
-Kylin depends on HDFS, MapReduce, Hive and HBase.
-Hive and MapReduce is used for cube building. Hive is used for pre-join and MapReduce is used for pre-aggregation.
-HDFS is used to store intermediated files during cube building.
-HBase is used to store data cube and answer the query. HBase coprocessor is also used for query processing.
