Amar Kamat updated MAPREDUCE-1482:
----------------------------------
Attachment: mapreduce-1482-v1.2.patch
Attaching a new patch incorporating Amareshwari's comment to do with logging of
diagnostic-info and state-string. Prior to this patch, state-string info was
already logged in the task-tracker and diag-info was logged at the jobtracker.
With this patch, the actual state-string info and diag-info will be logged in
task logs while the truncated strings will be logged in task-tracker and
jobtracker.
> Better handling of task diagnostic information stored in the TaskInProgress
> ---------------------------------------------------------------------------

> JobTracker.
