Hemanth Yamijala updated HADOOP-5282:
-------------------------------------
Attachment: HADOOP-5282-v1.2.patch
When I tried to apply the patch on Linux, it worked fine, but the same patch
did not work on people.apache.org. Hence just regenerated the patch on Linux
and uploading it.
As there's no difference at all in the patch, I will commit it.
> Running tasks on lost trackers are incorrectly logging the attempt and task
> failures
