Hari,

When you issue a shutdown to the master process, it performs a full cluster 
shutdown.  You don't have to issue regionserver stops from the shell, the 
Master takes care of it over RPC.

You can stop an individual regionserver (bin/hbase-daemon.sh stop regionserver) 
but if you're doing a full shutdown, it's best to do it through the master 
shutdown (bin/stop-hbase.sh).
