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).
