Robert Joseph Evans updated MAPREDUCE-4252:
-------------------------------------------
Target Version/s: 2.0.0-alpha, 0.23.3 (was: 2.0.0-alpha)
The patch applies with no changes to branch-0.23 as well. It would be great if
you could pull it in there too. For what it is worth a quick look at the patch
looks good, but I don't want to +1 it without a more in-depth look.

> This was found by ATM:

> 999 of the tasks had completed, the job is now sitting forever with 1 task
> "pending".
