Andrew Purtell commented on HBASE-16375:
----------------------------------------
Correct, you'd need to make a patch per branch. However in this case I think
it's fine to just put up a patch just for master. Precommit results will
generally apply and the committer can easily run the new test when applying the
patch to the other target branches to check there is not unexpected variation

> Starting mapreduce mini cluster using HBaseTestingUtility is not setting
> "yarn.resourcemanager.webapp.address" and
> "mapreduce.jobhistory.webapp.address" which are required for getting the
> submitted yarn apps using mapreduce webapp. These properties are not being
> copied from jobConf of MapReduceTestingShim resulting in default values.
