Hemanth Yamijala commented on HADOOP-5419:
------------------------------------------
Close, but a little more work:
- In displayQueueAclsInfoForCurrentUser, when no ACLs are returned, we are
using UserGroupInformation.getCurrentUGI().getUserName(). This could be null if
the login is not done, right ?
- I would recommend that the JobClient API be changed to
getQueueAclsForCurrentUser, and the java doc updated accordingly.
- QueueManager API need not be called getCurrentUserQueueAclsInfo, as we are
passing a UGI. Let's just call it getQueueAcls(UGI ugi)
- Javadoc for the QueueManager API is still saying 'current user' though we are
passing in the UGI.
- java.util.Iterator is not needed in QueueManager, I think, Can you check
- I think the formatting of the QueueAclsInfo in the toString is not right.
Let's keep all formatting in JobQueueClient API and remove the toString

> This issue is to provide an improvement on the existing M/R framework to let
> users know which queues they have access to, and for what operations. One use
> case for this would that currently there is no easy way to know if the user
> has access to submit jobs to a queue, until it fails with an access control
> exception.
