Mayank Bansal commented on MAPREDUCE-3837:
------------------------------------------
Thanks Tom for your comments. I incorporated everything except below point
bq. If there is no need for restart count anymore - since jobs are re-run from
the beginning each time - then would it be cleaner to remove it entirely?
Yeah you are right and we should cleanup the restart count, However it looks to
me it needs to be looked at more closely and more testing required. Do you mind
If I open a separate JIRA and work on that separately then this JIRA?
Rest of the comments are incorporated in my latest patch.
Thanks,
Mayank
