Subject [jira] [Created] (YARN-400) RM can return null application resource usage report leading to NPE in client
Date Tue, 12 Feb 2013 16:45:13 GMT
Jason Lowe created YARN-400:
-------------------------------

             Summary: RM can return null application resource usage report leading to NPE
in client
                 Key: YARN-400
                 URL: https://issues.apache.org/jira/browse/YARN-400
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 0.23.6, 2.0.3-alpha
            Reporter: Jason Lowe
            Assignee: Jason Lowe
            Priority: Critical


RMAppImpl.createAndGetApplicationReport can return a report with a null resource usage report
if full access to the app is allowed but the application has no current attempt.  This leads
to NPEs in client code that assumes an app report will always have at least an empty resource
usage report.
