Description

From https://issues.cloudera.org/browse/HUE-2608

"Oozie logs in Hue does not work well when Oozie is configured in HA mode. Essentially, DoAs user doesn't work for HA request. This happens because in HA one server will call other server as "tomcat user".

http://oozie-server:4080/oozie/v2/job/jobid1-oozie_CB-W?show=log&allservers=false&doAs=sumeet&user.name=hue
will be http://oozie-server:4080/oozie/v2/job/jobid1-oozie_CB-W?show=log&allservers=false&doAs=sumeet&user.name=oozie

Potential fixes can be to add oozie as proxy user or drop doAs user from server to server call. Since the request is already authenticated, it should ok to call other server with oozie user. http://oozie-server:4080/oozie/v2/job/jobid1-oozie_CB-W?show=log&allservers=false&user.name=oozie"
