Arun C Murthy commented on MAPREDUCE-4488:
------------------------------------------
The concern I have is that MAPREDUCE-463 is very different from the current JT.
Originally, I did this work for the 2009 terasort record and was since ported
over to branch-0.21. However, since then the locking in the JT has changed
significantly - hence my advise to revisit. Thoughts?
> Port MAPREDUCE-463 (The job setup and cleanup tasks should be optional) to
> branch-1
