> 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:
> {quote}
> 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.
