Thanks. What if I'm not able to login the region server(both ssh and local)? I have to reboot and check the server because of this serious problem.

You can use bin/graceful_stop.sh to stop the region server process.

# Move regions off a server then stop it.  Optionally restart and reload.
# Turn off the balancer before running this script.

After that, you can stop hadoop (datanode, etc)
