stack commented on HBASE-12613:
-------------------------------

bq. Still trying to figure out how to call 
HConnectionImplementation#getKeepAliveZooKeeperWatcher() in ruby

Cast the connection as a ClusterConnection then do getMaster and on the 
returned stub, call getServerName?

Suggest avoid directly referencing zk if possible.

> Master accepts online load of configuration changes.
> This JIRA adds shell support for this feature such that user doesn't need to 
> look up Master servername.
