Steve Loughran resolved YARN-2057.
----------------------------------
Resolution: Duplicate
> NPE in RM handling node update while app submission in progress
> ---------------------------------------------------------------
>
> Key: YARN-2057
> URL: https://issues.apache.org/jira/browse/YARN-2057
> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager
> Affects Versions: 2.4.0
> Environment: OS/X, hadoop 2.4.0 mini yarn cluster, slider unit test
> TestDestroyMasterlessAM
> Reporter: Steve Loughran
>
> One of our test runs finished prematurely with an NPE in the RM, followed by
> the RM thread calling system.exit(). It looks like an NM update came in while
> the app was still being set up, causing confusion.
