Owen O'Malley updated HADOOP-4209:
----------------------------------
Resolution: Fixed
Hadoop Flags: [Reviewed]
Status: Resolved (was: Patch Available)
I just committed this. Thanks, Amar!
I don't think this should be an incompatible change, because relative to 0.18,
all that changed was that the task attempt ids are formatted to always have 4
digits.
> The TaskAttemptID should not have the JobTracker start time
