----------------------------------------------------------------

Thanks [~elgoiri] for updating the patch. The latest patch is pretty close, 
couple of minor comments:
* Can you rebase (_get/put/createRootDirRecursively_ from {{ZKCuratorManager}}) 
now that HADOOP-14773 is in.
* Instead of adding in *yarn-default.xml*, I prefer to exclude in 
{{TestYarnConfigurationFields}} as ZK store is not the default store anyways.

> YARN-5408 defines the unified {{FederationStateStore}} API. Currently we only 
> support SQL based stores, this JIRA tracks adding a ZooKeeper based 
> implementation for simplifying deployment as it's already popularly used for 
> {{RMStateStore}}.
