Iyappan Srinivasan commented on MAPREDUCE-277:
----------------------------------------------

For the patch-277-0.20.txt,

+1 for QA

1) Checked job for counters and if job and task numbers are displayed correctly.
2) Checked when jobs reach 100, still the job and task numbers are displayed correctly without
any erros.
3) When a job is killed, counter info are not displayed and no exception gets thrown in task
tracker logs.
4) When JT restat happens, when some jobs are running and some jobs are waiting, still the
jobs get resubmitted and
then shows the counter information properly.
5) When JT restart happens, the previously existing job history files, still shows the couner
information properly.
6) When a task attempt is killed/ failed, and the overall job fails, still the counter info
is shown
7) When a task attempt is killed/ failed, and the overall job passes, still the counter info
is shown.
8) Checked the counter info with the real info in the done directory. it still shows it correctly.
9) Did job -history "<path of job output directory" - It works
