Amar Kamat updated HADOOP-4716:
-------------------------------
Attachment: HADOOP-4716-v1.patch
Attaching a patch that
- reduced max backoff so that the retries happen frequently
- cleared the _known-outputs_ structure so that the reducer doesnt consider
events not known to jobtracker
Tested on my box and works fine. Not tested it throughly though. Somethings
that would also help :
- decrease the num-maps from 50 to 30. This will reduce the test's runt time.
> testRestartWithLostTracker frequently times out
