[jira] [Commented] (YARN-5484) YARN client will still retry for many times on failover even though RM server throw AccessControlException

Bob.zhao commented on YARN-5484:
--------------------------------

I think just like other place on yarn where process AccessControlException to YarnException , here we can warp AccessControlException to YarnException :
{code}
 try {
      ....
    } catch (AccessControlException e) {
      throw new YarnException(e);
    }
{code}
Any ideas?

>             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 onle 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.
