YARN requires changing HDFS/MapReduce API/wire-protocol?  Can't it be done
in hadoop 3.x?

I like the sound of this.  So, if HDFS, say, went unscathed by the higher
level API and wire-protocol machinations, it could make its way out to a
2.0.0 (or 2.0.4) absent the -beta/-alpha tails?

That'd help us downstreamers (As is, just trying to explain our now
out-of-date hadoop dependency is a couple of pages of the hbase reference
guide [1] -- and we haven't started in on how you'd run against hadoop2).
