YARN-5694 does not apply to branch-2.7. Rebase required? Wrong Branch? See https://wiki.apache.org/hadoop/HowToContribute

> 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.
