>                 Key: YARN-5484
>                 URL: https://issues.apache.org/jira/browse/YARN-5484
>             Project: Hadoop YARN
>          Issue Type: Bug
>    Affects Versions: 2.9.0
>            Reporter: Bob.zhao
>
> 1. Enable yarn.acl.enable
> 2. Set up some queue for users on yarn, for example queue1 only for user1
> 3. Using user1 to submit app to queue1, it can run successfully.
> 4. Change user2 to submit app to queue1, it will not be permit submit to queue1.
> So, At RM server side, it will throw IOException(ClientRMService.java#submitApplication),
which is the parent  implementation of the AccessControlException(RMAppManager.java#createAndPopulateNewRMApp),
this IOException will be threw to client that cause yarn client  frequently failover for many
times. 
> We'b better avoid this behavior that if client got permission deny from server, it should
 try once and exit, no need to retry.
> This issue was introduced by YARN-4522.
