Someone might have a more graceful method of determining this but I've
found outputting that kind of data to counters is the most effective
way. Otherwise you could use stderr or stdout but then you would need to
mine the log data on each node to figure it out.

Subject: Is there a way to see what file killed a mapper?
I have a basic job that is dying, I think, on one badly compressed file.
Is there a way to see what file it is choking on? Via the job tracker I
can find the mapper that is dying but I cannot find a record of the file
that it died on.
Thank you for your help
