Junping Du created MAPREDUCE-6084:
-------------------------------------
Summary: Load MR Configuration from distributed cache rather than
individual node
Key: MAPREDUCE-6084
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6084
Project: Hadoop Map/Reduce
Issue Type: Bug
Affects Versions: 2.5.0
Reporter: Junping Du
Assignee: Junping Du
For rolling upgrade YARN & MapReduce component, we already support to submit
jobs against different versions of mapreduce jars based on distributed cache
(please refer MAPREDUCE-4421). However, this could bring up some potential
issues if old jar cannot find a new added class with new configurations that
upgrade together with Hadoop components. For details, please refer the proposal
in attachments.
