how to terminate a program in hadoop?

[ma qiang]

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!

./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.

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

no, the jobtracker will take care of that for you.

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.
