      Description

      Rethink for znode structure for RM HA is proposed in some JIRAs(YARN-659, YARN-1222). The motivation of this JIRA is quoted from Bikas' comment in YARN-1222:

      We should move to creating a node hierarchy for apps such that all znodes for an app are stored under an app znode instead of the app root znode. This will help in removeApplication and also in scaling better on ZK. The earlier code was written this way to ensure create/delete happens under a root znode for fencing. But given that we have moved to multi-operations globally, this isnt required anymore.
