Hi Experts, I have been working on the JIRA https://issues.apache.org/jira/browse/MAPREDUCE-4490 and attached MAPREDUCE-4490.patch which could fix this jira. I would like to contribute my patch to community, but encountered some issues.
MAPREDUCE-4490 is an issue on Hadoop-1.x versions, and my patch based on the latest code of origin/branch-1.2. However, current trunk bases on Yarn and does not has such issue any more. So my patch could not be applied on current trunk code, and it's actually no need to generate a similar patch on trunk at all. How to submit the patch MAPREDUCE-4490.patch only to origin/branch-1.2, not trunk? Is it allowed by Apache Hadoop? Thanks!
