Thomas Graves commented on MAPREDUCE-3417:
------------------------------------------
Also note that I tested with valid users and it still allows any user to view
the job details even though the job view acls are set to only the job runner.
That was with security on and also used a http filter so that the user id
actually shows up.
> job access controls not working app master and job history UI's

> Key: MAPREDUCE-3417
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-3417
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 0.23.0
> Reporter: Thomas Graves
> Priority: Critical
>
> tested with security on, no filters defined for httpserver, job acls set so
> that only I could view/modify the job. Then went to the web ui to app master
> and job history server and both allowed me to view the job details. The
> webui shows the user "webuser". The RM properly rejected my request
> although it was using user "Dr.Who".
