Enable the Oozie UI on CentOS RHEL Oracle Linux 7 PPC

You must manually create an Ooze UI when using the latest versions of Ambari and HDP.

Ext JS is GPL licensed software and is no longer included in builds of HDP 2.6. Because of this, the Oozie WAR file is not built to include the Ext JS-based user interface unless Ext JS is manually installed on the Oozie server. If you add Oozie using Ambari to an HDP 2.6.4 or greater stack, no Oozie UI will be available by default. If you want an Oozie UI, you must manually install Ext JS on the Oozie server host, then restart Oozie. During the restart operation, Ambari re-builds the Oozie WAR file and will include the Ext JS-based Oozie UI.
  1. Log in to the Oozie Server host.
  2. Download and install the Ext JS package.
    rpm -ivh extjs-2.2-1.noarch.rpm
  3. Remove the following file:
    rm /usr/hdp/current/oozie-server/.prepare_war_cmd
  4. Restart Oozie Server from Ambari Web.
    Ambari rebuilds the Oozie WAR file.
