             Summary: NPE introduced by YARN-4958 (The file localization process should allow...)
                 Key: YARN-5373
                 URL: https://issues.apache.org/jira/browse/YARN-5373
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 2.9.0
            Reporter: Haibo Chen
            Assignee: Haibo Chen


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