> RMAppState isn't a public facing enum like YarnApplicationState, so we shouldn't return
values or list filters that come from it. However, some Blocks and AppInfo are still using
RMAppState.
> It is not 100% clear to me whether or not fixing this would be a backwards-incompatible
change.  The change would only reduce the set of possible strings that the API returns, so
I think not.  We have also been changing the contents of RMAppState since 2.2.0, e.g. in YARN-891.
It would still be good to fix this ASAP (i.e. for 2.2.1).
