---------------------------------------
Just curious, if we remove the ZK node, after the drained RS and HMaster
restart, will the drained status respected?
> Remove RS entry from zk draining servers node while RS getting stopped

> When a RS is been decommissioned, we will add an entry into the zk node. This
> will be there unless the same RS instance is recommissioned.
> But if we want to scale down a cluster, the best path would be to
> decommission the RSs in the scaling down nodes. The regions in these RSs
> will get moved to live RSs. In this case these decommissioned RSs will get
> stopped later. These will never get recommissioned. The zk nodes will still
> be there under draining servers path.
> We can remove this zk node when the RS is getting stopped.
