[jira] [Created] (YARN-5694) ZKRMStateStore should only start its verification thread when in HA failover is not embedded

Daniel Templeton created YARN-5694:
--------------------------------------

             Summary: ZKRMStateStore should only start its verification thread when in HA failover is not embedded
                 Key: YARN-5694
                 URL: https://issues.apache.org/jira/browse/YARN-5694
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager
    Affects Versions: 3.0.0-alpha1
            Reporter: Daniel Templeton
            Assignee: Daniel Templeton


There are two cases.  In branch-2.7, the {{ZKRMStateStore.VerifyActiveStatusThread}} is always started, even when using embedded or Curator failover.  In branch-2.8, the {{ZKRMStateStore.VerifyActiveStatusThread}} is only started when HA is disabled, which makes no sense.  Based on the JIRA that introduced that change (YARN-4559), I believe the intent was to start it only when embedded failover is disabled.
