---------------------------------

             Summary: GHS should show N/A instead of null for the inaccessible information
                 Key: YARN-2598
                 URL: https://issues.apache.org/jira/browse/YARN-2598
             Project: Hadoop YARN
          Issue Type: Bug
          Components: timelineserver
    Affects Versions: 2.6.0
            Reporter: Zhijie Shen


When the user doesn't have the access to an application, the app attempt information is not visible to the user. ClientRMService will output N/A, but GHS is showing null, which is not user-friendly.
