-------------------------------

Hi [~bibinchundatt]
I am trying to under stand the patch. Pls correct me if I am wrong.

Here user submitted an app to a non-existent queue. And this patch is trying to look for acl check for the user in a queue. So an AccessControlException will be thrown in this case. But for non-existent queue, do we need this exception.? I think it can be YarnException.
