which node processed my job
Not sure if this is the right list for this question, but.
Is it possible to determine which host actually processed my MR job?
Regards,
Alan

Alan,
If you want to find this out after the job has finished execution,you
can also look at <jobname>.jar file created in the "history" folder by
the JobTracker. It contains information about the TaskTracker that
executed Map/Reduce tasks, their start times, end times, etc.

Hi,
InetAddress.getLocalHost() should give you the hostname for each mapper/reducer
