Hi，
My hadoop cluster has been running for a period of time. Now i want to
close it for some system changes. But the command "bin/stop-all.sh" shows
"no jobtracker to stop","no tasktracker to stop","no namenode to stop" and
"no datanode to stop". I use "jps" got nothing but jps itself. However
you must using the same account that start your cluster.

Just send the processes a SIGTERM signal (regular kill). Its what the
script does anyway. Ensure to change the PID directory before the next
restart though.

ps aux|grep java , you can find pid, then just 'kill -9' to stop the
Hadoop process.

Hey Azuryy,
The -9 (SIGKILL) is unnecessary and isn't recommended unless its
unresponsive. The SIGTERM has an additional benefit of running any
necessary shutdown handling procedures, but SIGKILL is instant death.

Yes Harsh, It's my fault.
