With this info it is difficult to find out where the problem is coming. Can
you check the job tracker and task tracker logs related to these jobs?

Subject: Map job hangs indefinitely



I am starting a job from the map of another job. Following are quick mock of
the code snippets that I use. But the 2nd job hangs indefinitely after the
1st task attempt fails. There is not even a 2nd attempt. This runs fine on a
cluster with one node but fails on a two node cluster.

Can someone help me in understanding why the failed attempt was unable to be
rescheduled and thereby hangs the job.
