Interrupting JobClient.runJob

[Edwin <ed...@gmail.com>]

Hi

I am looking for a way to interrupt a thread that entered
JobClient.runJob(). The runJob() method keep polling the JobTracker until
the job is completed. After reading the source code, I know that the
InterruptException is caught in runJob(). Thus, I can't interrupt it using
Thread.interrupt() call. Is there anyway I can interrupt a polling thread
without terminating the job? If terminating the job is the only way to
escape, how can I terminate the current job?

Thank you very much.

Regards
Edwin

Yes. there is noway to stop the client from polling.
If you want to Stop client thread, use <ctrl>+c or kill the client 
process itself.

You can kill a job using the command:
bin/hadoop job -kill <jobid>
