how to terminate a program in hadoop?
Dear colleagues:
I use eclipse to develop some programs in hadoop, when
exceptions took place such as death cycle, I don't know how to
terminate it safely. Can you tell me? Thank you very much!
Best wishes!

So I must terminate these jobs using this method you mentioned on all
the computers in my cluster, am I right?

The web interface can also be used. This is handy if you are following the
progress of the job via the web.
Scroll to the bottom of the page.

./bin/hadoop job -Dmapred.job.tracker=<jobtracker_host>:<jobtracker_port>
-kill <jobname>
you can find the required constants by pointing your browser to your
jobtracker.
