[jira] [Created] (YARN-3228) Deadlock altering user resource queue

Christian Hott created YARN-3228:
------------------------------------

             Summary: Deadlock altering user resource queue
                 Key: YARN-3228
                 URL: https://issues.apache.org/jira/browse/YARN-3228
             Project: Hadoop YARN
          Issue Type: Bug
          Components: capacityscheduler, resourcemanager, scheduler
    Affects Versions: 2.0.1-alpha
         Environment: hadoop yarn, postgresql 
            Reporter: Christian Hott
            Priority: Blocker


let me introduce you with my problem:
all of this began after we created some resources queues on postgresql,
well we created it, assign it to the users and all was fine...
until we run a process (a large one iterative query) and I do an Alter Role over the user and the resource queue that he was using, before that I can't login whit the user and got a message saying "deadlock detection, locking against self"
does you have any idea why this for? or if have any comprensible log in to I can search for more information?
