Kylin OLAP

Overview

Extreme OLAP Engine for Big Data

An open source distributed Analytical Engine from eBay GDI team to provide SQL interface and multi-dimensional analysis (OLAP) on Hadoop to support TB to PB size analysis.

Getting Started

Prerequisites

Hadoop

Hadoop: 2.2.0.2.0.6.0-61 or above
Hive: 0.12.0.2.0.6.0-61 or above
HBase: 0.96.0.2.0.6.0-61-hadoop2

Kylin Server

Command hadoop, hive, hbase is workable on your hadoop cluster
JDK Runtime: JDK7 (OpenJDK or Oracle JDK)
Maven
Git
Tomcat
Mysql

Before Install

Mysql: mysql is running and user “root@localhost” without password is ready.
For the quick tutorial, we assume that your hadoop has priviledges disabled which means any user could run hadoop and hive command
CATALINA_HOME is set

Building Kylin

To compile Kylin from source code, clone from this repository and run:

mvn clean compile

Kylin will run as web server for user to interactive with it, to generate deployment package (war file) for host on J2EE application server:

mvn clean package

Kylin has a comprehensive set of unit tests that can take long time to run especially for cube generation. You can disable the tests when building:

mvn clean package -DskipTests

Run Kylin

To run Kylin, deploy geneated war file into J2EE application server like Tomcat, and restart application server. then access from browser via following URL: [http://<localhost>:<port>/<application name>]
