Hemanth Yamijala commented on HADOOP-5282:
------------------------------------------
Looked at the patch. This looks fine. One minor comment is to replace the
nested conditional statement with a more clear if..else if..else block as it is
really hard to read the current code.
Please run test-patch and ant tests and upload the results.
> Running tasks on lost trackers are incorrectly logging the attempt and task
> failures
