TBC this is an upstream YARN thing, and not anything specific to CDH. There
are to my knowledge at least three incompatible versions, and they're all in
use out there. It is shipped as non-stable everywhere before 2.2 and is
actually a separate project from core Hadoop. It may in truth require 3
separate profiles, or a tweak to make 1 profile work across two versions. I had
hoped `yarn` might happen to work across beta/stable work but am doubting that
even that is true, because of protobuf. Worth verifying.
