>             Project: Hadoop YARN
>          Issue Type: Bug
>          Components: nodemanager
>    Affects Versions: 2.9.0
>            Reporter: Haibo Chen
>            Assignee: Daniel Templeton
>            Priority: Blocker

> YARN-4958 added support for wildcards in file localization. It introduces a NPE 
> at 
> {code:java}
> for (File wildLink : directory.listFiles()) {
>     sb.symlink(new Path(wildLink.toString()), new Path(wildLink.getName()));
> }
> {code}
> When directory.listFiles returns null (only happens in a secure cluster), NPE will cause
the container fail to launch.
> Hive, Oozie jobs fail as a result.
