Installing Ext JS to Support Oozie UI

Oozie UI depends on the Ext JS JavaScript framework, and you must manually install Ext JS on your cluster.

Note

These steps apply for clusters using Cloudera Distribution including Apache Hadoop.

Ext JS is a JavaScript framework for building data-intensive, cross-platform web and mobile applications. Big Data Service requires Ext JS 2.2 placed in the Oozie webapp directory to make Oozie UI work. Ext JS is licensed under GPLv2.

To install Ext JS 2.2:

  1. Download ext2.2.zip from http://archive.cloudera.com/gplextras/misc/ext-2.2.zip.
  2. Copy the zip file to a cluster node where Oozie server is installed, and unzip it there.
  3. Place the unzipped directory, with name ext-2.2, in /usr/lib/oozie/embedded-oozie-server/webapp/ and verify that ownership of the directory is with oozie:hadoop.
