Thomas Graves commented on SPARK-1898:
--------------------------------------
That is correct, as long as you don't modify anything in common or yarn-alpha
0.23 and really early 2.0 versions aren't affected. I think he was referring
to all the various 2.X releases though. Unfortunately api's have changed in
the early version up until the the stable release of 2.2. I think the other
problem we've seen is not all the various vendor releases mapping straight to
an apache release.
Ideally this shouldn't be a problem but it should be sufficiently tested on all
we say we support. Based on that, I agree with @tdas, unless this is a real
blocker and you can explain why we should wait to put this in and fix as many
of the api's as possible in a follow on release.

> In {{deploy.yarn.Client}}, we should use {{YarnClient}} rather than
> {{YarnClientImpl}}. The latter is annotated as {{Private}} and {{Unstable}}
> in Hadoop, which means it could change in an incompatible way at any time.
