how to close hadoop when tmp files were cleared

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, 
hadoop is indeed running.I think it may be some tmp files about hadoop had 
been cleared by operation system. Could someone tell me how to stop hadoop 
in case of no data files breaks ?
Any guidance would be greatly appreciated. Thanks!

Jeff

Yes, i use the same account named "hadoop".

Using "ps aux|grep java" could find hadoop is running, i forgot to change
the "HADOOP_PID_DIR" parameter, and operation system must cleared the pid
files.

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.

Re: how to close hadoop when tmp files were cleared

necessary shutdown handling procedures, but SIGKILL is instant death.
