> Typing "hbase master stop" produces the following message:
> "stop   Start cluster shutdown; Master signals RegionServer shutdown"
> It seems like backup masters should be considered part of the cluster, but they are not
brought down by "hbase master stop".
> "stop-hbase.sh" does correctly bring down the backup masters.
> The same behavior is observed when a client app makes use of the client API HBaseAdmin.shutdown()
http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/client/HBaseAdmin.html#shutdown()
-- this isn't too surprising since I think "hbase master stop" just calls this API.
> It seems like HBASE-1448 address this; perhaps there was a regression?
