-------------------------------------
Summary: Distributed cache conflicts breaks backwards compatability
Key: MAPREDUCE-7118
URL: https://issues.apache.org/jira/browse/MAPREDUCE-7118
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Affects Versions: 3.1.0, 3.0.0, 3.2.0
Reporter: Jason Lowe
Assignee: Jason Lowe
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.
