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).

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)
