| |
| Here are quick start steps : |
| |
| Before starting the server, you need to set HADOOP_HOME and HIVE_HOME environment variables. These should point to |
| the Hadoop and Hive installation directories. Lens depends on a forked version of Hive which is available at |
| https://github.com/inmobi/hive. So, Hive needs to be built and HIVE_HOME should be set as packaged directory from |
| build. |
| |
| Building hive : |
| $ git clone https://github.com/inmobi/hive |
| $ git checkout hive-release-0.13.3-inm |
| $ mvn clean package -DskipTests -Phadoop-2,dist |
| |
| Server packaging is server/ folder. |
| $ cd server |
| |
| Starting lens server : |
| bin/lens-ctl start |
| |
| Lens server also comes with simple UI service which can be used to browse catalog and submit queries. Once the server |
| starts up, you can open the UI service on http://<serverhost>:19999/index.html and browse. |
| |
| Client distribution is in client/ folder. |
| |
| $ cd client |
| |
| Running examples : |
| $ bin/run-examples sample-metastore |
| $ bin/run-examples populate-metastore |
| $ bin/run-examples runqueries |
| |
| Starting lens cli : |
| bin/lens-cli.sh |
| |
| Stopping Lens server : |
| bin/lens-ctl stop |
