Bikas Saha commented on YARN-1307:
----------------------------------
After looking at the code I understand what you mean by the suffix numbers. Its
the _1, _2 in the tree above for token and key. I think its fine to use the
current approach that uses sequence number for tokens and key id for secret
keys. Or we can name them serially as 1,2,3... etc like you describe above.
Either is fine. We will soon be batching them into znodes anyways in the near
future.
Above looks good.

> 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.
