Thanks Harsh.
I did look at userlogs dir. Although it creates subdirs for each
job/attempt, there are no files in those directories. just the acl xml file.
I had also looked at task tracker log and all it has is this -
2011-09-30 15:50:05,344 INFO org.apache.hadoop.mapred.TaskTracker:

Vinod,
There should be some stderr information on the task attempts' userlogs
that should help point out why your task launching is failing. It is
probably cause of something related to the JVM launch parameters (as
defined by mapred.child.java.opts).
If not there, look into the TaskTracker logs
I just setup a pseudo-distributed hadoop setup. but when i run the example
task, i get failed child error. I see that this was posted earlier as well
but I didn't see the resolution.
