Mayank Bansal commented on MAPREDUCE-5900:
------------------------------------------
Hi Wangda,
I dont think we can add checkpointing as of now. I think we don't need
TA_PREEMTION transition as of now and KILL is suffice. However when we add
checkpointing then that patch will automatically take care of that.
Thanks,
Mayank
