> NPE getting application report with a null appId
> ------------------------------------------------
>
> Key: YARN-1556
> URL: https://issues.apache.org/jira/browse/YARN-1556
> Project: Hadoop YARN
> Issue Type: Bug
> Components: client
> Affects Versions: 2.7.1
> Reporter: Steve Loughran
> Assignee: Weiwei Yang
> Priority: Trivial
> Fix For: 2.8.0
>
> Attachments: YARN-1556.patch
>
>
> If you accidentally pass in a null appId to get application report, you get
> an NPE back. This is arguably as intended, except that maybe a guard
> statement could report this in such a way as to make it easy for callers to
> track down the cause.
