> 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.
