[jira] [Created] (YARN-6598) History server getApplicationReport NPE when fetching report for pre-2.8 job

Jason Lowe created YARN-6598:
--------------------------------

             Summary: History server getApplicationReport NPE when fetching report for pre-2.8 job
                 Key: YARN-6598
                 URL: https://issues.apache.org/jira/browse/YARN-6598
             Project: Hadoop YARN
          Issue Type: Bug
          Components: timelineserver
    Affects Versions: 2.8.0
            Reporter: Jason Lowe
            Assignee: Jason Lowe
            Priority: Blocker


ApplicationHistoryManagerOnTimelineStore#convertToApplicationReport can NPE for a job that was run prior to the cluster upgrading to 2.8.  It blindly assumes preemption metrics are present when CPU metrics are present, and when they are not it triggers the NPE.
