Hi,

I am getting following errors -

I see following error in task tracker log :-

2012-12-03 17:09:40,969 INFO org.apache.hadoop.mapred.TaskTracker.clienttrace: src: 192.168.156.22:50060,

What could be the reason behind it ? The job should have finished in 10 min. but it's going
on and on for hours.
