RE: Unknown processes unable to terminate
Hi Sai,

   The RunJar process is normally the result of someone or something running “hadoop jar <something>”
   (i.e:  org.apache.hadoop.util.RunJar  <something>)

   You probably want to find out who/what is running with a more detail info via ps –ef | grep RunJar
   <stop|start>-all.sh deals with hdfs/ M/R specific process only.   So it will not stop any other java process reported by jps.

I have a list of following processes given below, i am trying to kill the process 13082 using:

kill 13082

Its not terminating RunJar.

I have done a stop-all.sh hoping it would stop all the processes but only stopped the hadoop related processes.
I am just wondering if it is necessary to stop all other processes before starting the hadoop process and how to stop these other processes.

Here is the list of processes which r appearing:
30969 FileSystemCat
30877 FileSystemCat
5647 StreamCompressor
32200 DataNode
25015 Jps
2227 URLCat
5563 StreamCompressor
5398 StreamCompressor
13082 RunJar
32578 JobTracker
385 TaskTracker
31884 NameNode
32489 SecondaryNameNode
