-----------------------------------------
Thanks for fixing this [~jlowe] - we actually took care of this in OOZIE-3227.

> Key: MAPREDUCE-7118
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-7118
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 3.0.0, 3.1.0, 3.2.0
> Reporter: Jason Lowe
> Assignee: Jason Lowe
> Priority: Blocker
> Attachments: MAPREDUCE-7118.001.patch

>
> MAPREDUCE-4503 made distributed cache conflicts break job submission, but
> this was quickly downgraded to a warning in MAPREDUCE-4549. Unfortunately
> the latter did not go into trunk, so the fix is only in 0.23 and 2.x. When
> Oozie, Pig, and other downstream projects that can occasionally generate
> distributed cache conflicts move to Hadoop 3.x the workflows that used to
> work on 0.23 and 2.x no longer function.
