There are multiple ways to debug map reduce programs. I found comfortable
using the jobtracker web UI. You can your job tracker web UI at
http://:50030/jobtracker.jsp
Open it in a browser.
There you can find the running,fa
tracker log levels from there.
Mostly I get the root cause of my job failures from there.
Hope it helps
