+
+### 1. Authentication
+* Currently, Kylin uses [basic authentication](http://en.wikipedia.org/wiki/Basic_access_authentication).
+* Add `Authorization` header to first request for authentication
+* Or you can do a specific request by `POST http://localhost:7070/kylin/api/user/authentication`
+* Once authenticated, client can go subsequent requests with cookies.
+* Example
+{% highlight Groff markup %}
+ POST http://localhost:7070/kylin/api/user/authentication
+
+ Authorization:Basic xxxxJD124xxxGFxxxSDF
+ Content-Type: application/json;charset=UTF-8
+{% 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.
+* Example
+{% highlight Groff markup %}
+ GET http://localhost:7070/kylin/api/cubes?cubeName=test_kylin_cube_with_slr&limit=15&offset=0
+
+ Authorization:Basic xxxxJD124xxxGFxxxSDF
+ Content-Type: application/json;charset=UTF-8
+{% endhighlight %}
+### 3. Then submit a build job of the cube.
+* `PUT http://localhost:7070/kylin/api/cubes/{cube_name}/rebuild`
+* For put request body detail please refer to [service doc](https://github.com/KylinOLAP/Kylin/wiki/Restful-Service-Doc).
+ * `startTime` and `endTime` should be utc timestamp.
+ * `buildType` can be `BUILD` or `MERGE`. `BUILD` is for building a new segment or refreshing an existing segment. `MERGE` is for merging multiple existing segments into one bigger segment.
+* This method will return a newly created job instance, in which the uuid is the identity of job to track job status.
+* Example
+{% highlight Groff markup %}
+ PUT http://localhost:7070/kylin/api/cubes/test_kylin_cube_with_slr/rebuild
+
+ Authorization:Basic xxxxJD124xxxGFxxxSDF
+ Content-Type: application/json;charset=UTF-8
+
+ {
+ "startTime": 0,
+ "endTime": 1388563200000,
+ "buildType": "BUILD"
+ }
+{% endhighlight %}
+
+### 4. Track job status.
+* `GET http://localhost:7070/kylin/api/jobs/{job_uuid}`
+* Returned `job_status` represents current status of job.
+
+### 5. If the job failed, you can resume the job.
+* `PUT http://localhost:7070/kylin/api/jobs/{job_uuid}/resume`

+version: v0.7.2
+since: v0.6

+
+Off-Hadoop-CLI installation is usually for **development use**.
+
+Developers want to run kylin test cases or applications at their development machine. The scenario is depicted at [https://github.com/KylinOLAP/Kylin#off-hadoop-cli-installation](https://github.com/KylinOLAP/Kylin#off-hadoop-cli-installation).
+
+
+By following this tutorial, you will be able to build kylin test cubes by running a specific test case, and you can further run other test cases against the cubes having been built.
+
+
+## Environment on the Hadoop CLI
+
+Off-Hadoop-CLI installation requires you having a hadoop CLI machine (or a hadoop sandbox) as well as your local develop machine. 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 2.2**.
+
+### Start Hadoop
+
+In Hortonworks sandbox, ambari helps to launch hadoop:
+
+{% highlight Groff markup %}
+ ambari-agent start
+ ambari-server start
+{% endhighlight %}
+
+With both command successfully run you can go to ambari home page at <http://yoursandboxip:8080> (user:admin,password:admin) to check everything's status. By default ambari disables Hbase, you'll need manually start the `Hbase` service.
+
+For other hadoop distribution, basically start the hadoop cluster, make sure HDFS, YARN, Hive, HBase are running.
+
+
+## Environment on the dev machine
+
+
+### Install maven
+
+The latest maven can be found at <http://maven.apache.org/download.cgi>, we create a symbolic so that `mvn` can be run anywhere.
+
+{% highlight Groff markup %}
+ cd ~
+ wget http://xenia.sote.hu/ftp/mirrors/www.apache.org/maven/maven-3/3.2.5/binaries/apache-maven-3.2.5-bin.tar.gz
+ tar -xzvf apache-maven-3.2.5-bin.tar.gz
+ ln -s /root/apache-maven-3.2.5/bin/mvn /usr/bin/mvn
+{% endhighlight %}
+
+### Compile
+
+First clone the Kylin project to your local:
+
+{% highlight Groff markup %}
+ git clone https://github.com/KylinOLAP/Kylin.git
+{% endhighlight %}
+
+Install Kylin artifacts to the maven repo
+
+{% highlight Groff markup %}
+ mvn clean install -DskipTests
+{% endhighlight %}
+
+### Modify local configuration
+
+Local configuration must be modified to point to your hadoop sandbox (or CLI) machine.
+
+* In **examples/test_case_data/sandbox/kylin.properties**
+ * Find `sandbox` and replace with your hadoop hosts (if you're using HDP sandbox, this can be skipped)
+ * Fine `kylin.job.run.as.remote.cmd` and change it to "true" (in code repository the default is false, which assume running it on hadoop CLI)
+ * Find `kylin.job.remote.cli.username` and `kylin.job.remote.cli.password`, fill in the user name and password used to login hadoop cluster for hadoop command execution; If you're using HDP sandbox, the default username is "root" and password is "hadoop".
+
+* In **examples/test_case_data/sandbox**
+ * For each configuration xml file, find all occurrence of `sandbox` and replace with your hadoop hosts; (if you're using HDP sandbox, this can be skipped)
+
+An alternative to the host replacement is updating your `hosts` file to resolve `sandbox` and `sandbox.hortonworks.com` to the IP of your sandbox machine.
+
+### Run unit tests
+
+Run a end-to-end cube building test
+
+{% highlight Groff markup %}
+ mvn test -Dtest=com.kylinolap.job.BuildCubeWithEngineTest -DfailIfNoTests=false
+{% endhighlight %}
+
+Run other tests, the end-to-end cube building test is exclueded
+
+{% highlight Groff markup %}
+ mvn test
+{% endhighlight %}
+
+### Launch Kylin Web Server
+
+In your Eclipse IDE, launch `com.kylinolap.rest.DebugTomcat` with specifying VM arguments "-Dspring.profiles.active=sandbox". (By default Kylin server will listen on 7070 port; If you want to use another port, please specify it as a parameter when run `DebugTomcat)
+
+Check Kylin Web available at http://localhost:7070/kylin (user:ADMIN,password:KYLIN)
+

+categories: development
+permalink: /docs/development/javascript_api.html
+version: v0.7.2
+since: v0.7.1
+---
+Kypin securicty authorization is based on basic access authorization, so when you want to use API in your javascript,you need to involve the authorization info in http headers.
+
+## Here is a demo show how to use Kylin 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,"partial":true,"project":"test"}',
+ dataType: "json"
+ });
+ request.done(function( msg ) {
+ alert(msg);
+ });
+ request.fail(function( jqXHR, textStatus ) {
+ alert( "Request failed: " + textStatus );
+ });
+
+```
+
+
+For what is basic access authorization ,click here http://en.wikipedia.org/wiki/Basic_access_authentication
+
+## Keypoint:
+1. add basic access authorization info in heders.
+2. use right ajax type and right data synax
+
+How to generate your authorization code (download and import "jquery.base64.js" from 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'
+ }
+});
+```

+
+## Enabling LZO compression
+
+LZO compression can be leveraged to compress the output of MR jobs, as well as hbase table storage, reducing the storage overhead. By default we do not enable LZO compression in Kylin because hadoop sandbox venders tend to not include LZO in their distributions due to license(GPL) issues.
+
+To enable LZO in Kylin, there are three steps:
+
+### Make sure LZO is working in your environment
+
+we have a simple tool to test whether LZO is well installed and configured in your environment(we only test it on the hadoop CLI that you deployed Kylin), Just run
+
+{% highlight Groff markup %}
+hbase org.apache.hadoop.util.RunJar kylin-job-latest.jar com.kylinolap.job.tools.LZOSupportnessChecker
+{% endhighlight %}
+
+If the program prints "LZO supported by current env? true", you're good to go. Otherwise you'll need to first install LZO properly.
+
+### Modify kylin_job_conf.xml
+
+You'll need to stop Kylin first by running `./kylin.sh stop`, and then modify /etc/kylin/kylin_job_conf.xml by uncommenting some configuration entries related to LZO compression.
+
+### export KYLIN_LD_LIBRARY_PATH to carry your native library paths
+
+Before running `./kylin.sh start` again, you'll need to export KYLIN_LD_LIBRARY_PATH to carry your LZO native library paths. If you are not sure where it is, you can simply find it in /tmp/kylin_retrieve.sh, Kylin retrieved this from hbase, normally this should work. Here's an example for hdp 2.1:
+
+{% highlight Groff markup %}
+export KYLIN_LD_LIBRARY_PATH=::/usr/lib/hadoop/lib/native/Linux-amd64-64:/usr/lib/hadoop/lib/native
+{% endhighlight %}
+
+After exporting, you need to run `./kylin.sh start` to start Kylin again. Now Kylin will use LZO to compress MR outputs and hbase tables.

+
+### Environment
+
+Kylin Rquires a properly setup hadoop environment to run. Following are the minium request to run Kylin, for more detial, please check this reference: [Hadoop Environment](hadoop_env.html).
+
+## Prerequisites on Hadoop
+
+* Hadoop: 2.4+
+* Hive: 0.13+
+* HBase: 0.98+
+* JDK: 1.7+
+_Tested with Hortonworks HDP 2.2 and Cloudera Quickstart VM 5.1_
+
+
+On-Hadoop-CLI installation is the most common way of installing Kylin. 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 components in Hadoop CLI, 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.incubator.apache.org/download](http://kylin.incubator.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 just 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 instances 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.md)

+
+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
+{% 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 3
+{% endhighlight %}
+
+You can specify the number of nodes you'd like to have in your cluster (3 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
+{% 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](https://github.com/KylinOLAP/Kylin/wiki/Kylin-Cube-Creation-Tutorial).
