Kai Zheng commented on HADOOP-13218:
------------------------------------
Sorry for the inconvenience. I'll fire a new JIRA and sort out a fix soon.
The cause should that the default engine should remain as the old one, before
MAPREDUCE-6706 is solved. The fix should be simple in YARN/MapReduce side so
necessary test cases are involved and triggered.

> Patch for HADOOP-12579 contains lots of work to migrate the left Hadoop side
> tests basing on the new RPC engine and nice cleanups. HADOOP-12579 will be
> reverted to allow some time for YARN/Mapreduce side related changes, open
> this to recommit most of the test related work in HADOOP-12579 for easier
> tracking and maintain, as other sub-tasks did.
