Jonathan Eagles commented on MAPREDUCE-3417:
--------------------------------------------
One aspect of the issue I notice. There is a difference in
hadoop.security.authentication=simple for accessing the tracking url via the
proxy and accessing via the AM directly. The proxy address allows access for
invalid users while the AM address disallows access for invalid users(proxy not
forwarding on remote user for simple security?)
> 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".
