Hi,

I am using a cluster of two machines one master and one slave. When i
try to stop the cluster using stop-all.sh it is displaying as below. the
task tracker and datanode are also not stopped in the slave. Please help me
in solving this.

Inside hadoop-env.sh, you will see a property that sets the directory for
pids to be written too. Check which directory it is and then investigate
the possibility that some other process is deleting, or overwriting those
files. If you are using NFS, with all nodes pointing at the same
directory,
then it might be a matter of each node overwriting the same file.

Either way, the stop scripts look for those pid files, and used them to
stop
the correct daemon. If they are not found, or if the file contains the
wrong pid, the script will echo no process to stop.
