Bibin A Chundatt created YARN-5845:
--------------------------------------

             Summary: Skip aclUpdated event publish to timelineserver or recovery
                 Key: YARN-5845
                 URL: https://issues.apache.org/jira/browse/YARN-5845
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Bibin A Chundatt
            Assignee: Bibin A Chundatt
            Priority: Critical


Currently ACL update event is send to timeline server even on recovery {{RMAppManager#createAndPopulateNewRMApp}}.
For 10K completed application when RM is restarted 10K ACL updated event is added to timelinesever
causing unnecessary over loading of system

{code}
    String appViewACLs = submissionContext.getAMContainerSpec()
        .getApplicationACLs().get(ApplicationAccessType.VIEW_APP);
    rmContext.getSystemMetricsPublisher().appACLsUpdated(
        application, appViewACLs, System.currentTimeMillis());
{code}
*Events on each RM restart*
