Tsuyoshi OZAWA commented on YARN-659:
-------------------------------------
Hi [~jianhe], ZK doesn't support 'directory removal'. But we can do it with
multi ops API with stats as follows:
1. Call getChildren to get all attempt ids.
2. Call getData to get all stats of attempt ids' node.
3. Call multi List<Op.delete> with version numbers of attempts ids.
> RMStateStore's removeApplication APIs should just take an applicationId

> There is no need to give in the whole state for removal - just an ID should
> be enough when an app finishes.
