Yes, I've already stopped the balancer and manually moved the regions to
other servers. Now I'm decommissioning the dfs data node on the server.
After that I will reboot the server.

Hi Rural,
Decomission the node, stop the processes, and reboot. You can look at the
scripts in bin/ to help you with that. Like bin/graceful_stop.sh.

Hi,
I have one region server which needs to be rebooted for server
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)

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.

Actually I have to do a hard reboot. Let me provide more info about the
problem: Except the ssh service(ssh error is:
ssh_exchange_identification: Connection closed by remote host) and local
login problem, other services are running fine on the server(including
http/ftp/hbase/hadoop etc).

Disable load balancer, and move all the regions manually to other hosts
