Package & deploy

Get war package

  • Tez UI is distributed as a war package.
  • To build & package UI without running test cases, run mvn clean package -DskipTests in this directory.
  • This would give you a war file in ./target.
  • UI build is part of tez build, refer BUILDING.txt for more info.

Using UI war


Use webfront tomcat manager to upload & deploy your war remotely.


The war can be added to any tomcat instance.

  1. Remove any old deployments in $TOMCAT_HOME/webapps
  2. Copy the war to $TOMCAT_HOME/webapps
  3. Restart tomcat and the war will get deployed. The content of the war would be available in $TOMCAT_HOME/webapps/tez-ui-[version] directory.


All the following commands must be run inside src/main/webapp.


You will need the following things properly installed on your computer.

  • Install Node.js (with NPM)
  • Install Bower
  • Install all dependencies by running npm install & bower install
