Kylin on Docker

This repository trackes the code and files for building docker images with Apache Kylin.

Please note: this is the master branch, which doesn't have the scripts and Dockerfile; You need checkout the specific branch which named with Kylin version and Hadoop release name.


Apache Kylin is an open source Distributed Analytics Engine designed to provide SQL interface and multi-dimensional analysis (OLAP) on Hadoop supporting extremely large datasets. For more information you can visit Kylin home page at

Usually Kylin is deployed in a dedicated Hadoop client node, on which the Hadoop, HBase, Hive and other clients have been properly configured to communicate with the cluster; Kylin will use the client Jars and configuration files to work with other components; Besides, all Kylin metadata and cube data are persistended in HBase and HDFS, not in local, so all these make it very reasonable to build Kylin as a docker image for quick deploy.

How to make it

The main idea is building Hadoop/HBase/Hive clients and Kylin binary package into one image; User can pull this image, and then just add client configuration files like core-site.xml, hdfs-site.xml, yarn-site.xml, hbase-site.xml, hive-site.xml and to the effective paths to make a new image (has verified), or upload these files during starting up (not verified yet);

Before start, you need do some preparations:

  • check the Hadoop versions, and make sure the client libs in the image are compitable with the cluster;
  • prepare a file for this deployment;
  • ensure the Hadoop security constraint will not block Docker's adoption; you may need run additional component in the container if kerberos is enabled.


Below is a sample of building and running a docker image for Hortonworks HDP 2.2 cluster.

  1. Collect the client configuration files Get the *-site.xml files from a working Hadoop client node, to a local folder say "~/hadoop-conf/";

  2. Prepare

The file is the main configuration file for Kylin; you need prepare such a file and put it to the "~/hadoop-conf/" folder, together with other conf files; suggest to double check the parameters in it; e.g, the "kylin.metadata.url" points to the right metadata table, "kylin.hdfs.working.dir" is an existing HDFS folder and you have permission to write, etc.

  1. Clone this repository, checkout the correct branch;
git clone  
cd kylin-docker  
git checkout kylin152-hdp22  
  1. Copy the client configuration files to "kylin-docker/conf" folder, overwriting those template files;
cp -rf ~/hadoop-conf/* conf/
  1. Build docker image, which may take a while, just take a cup of tea;
docker build -t kyligence/kylin:152 .

After the build finished, should be able to see the image with "docker images" commmand;

[root@ip-10-0-0-38 ~]# docker images  
REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE  
kyligence/kylin     152                 7ece32097fa3        About an hour ago   3.043 GB  
  1. Now you can run a contianer with the bootstrap command (in which will start Kylin server). The "-bash" argument is telling to keep in bash so you can continue to run bash commands; If don't need, you can use the "-d" argument:
[root@ip-10-0-0-38 ~]# docker run -i -t -p 7070:7070 kyligence/kylin:152 /etc/ -bash

A new Kylin instance is started by , stop it using " stop"  
Please visit http://<ip>:7070/kylin  
You can check the log at /usr/local/kylin/bin/..//logs/kylin.log  
  1. After a minute, you can open web browser with address http://host:7070/kylin , here the "host" is the hostname or IP address of the hosting machine which runs Docker; Its 7070 port will redirect to the contianer's 7070 port as we specified in the "docker run" command; You can change to other port as you like.

  2. Now you can use Kylin as usually: import Hive tables, design cubes, build, query, etc.


Thanks to SequenceIQ's hadoop-docker and other projects, which inspires us on developing this.

You can’t perform that action at this time.
