[jira] [Created] (YARN-4355) NPE while processing localizer heartbeat

Jason Lowe created YARN-4355:
--------------------------------

             Summary: NPE while processing localizer heartbeat
                 Key: YARN-4355
                 URL: https://issues.apache.org/jira/browse/YARN-4355
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 2.7.2
            Reporter: Jason Lowe


While analyzing YARN-4354 I noticed a nodemanager was getting NPEs while processing a private localizer heartbeat.  I think there's a race where we can cleanup resources for an application and therefore remove the app local resource tracker just as we are trying to handle the localizer heartbeat.
