Subru Krishnan commented on YARN-6900:

Thanks [~elgoiri] for updating the patch. The latest version is very close, couple of minor
* Based on the discussion with [~zhz]/[~leftnoteasy]/[~drankye] in YARN-6840, we should simply
merge what you have in {{YarnZKUtils}} in {{ZKUtils}} in hadoop-common.
* I am aware the util code is covered as part of the individual store tests but do you think
it makes sense to add some basic tests?
* Looks like you missed including the documentation update in the patch.

SQL based stores, this JIRA tracks adding a ZooKeeper based implementation for simplifying
deployment as it's already popularly used for {{RMStateStore}}.
