Steve Loughran commented on SLIDER-423:
---------------------------------------
thinking some more, I don't think there's easy and reliable way to validate
versions, except at the very major "does it begin with a 2. or 3." check —and
the AM/client won't know if it is compatible with future versions.
there's also the problem of "even if slider is compatible, what about the app
version?"
> slider-client should fail gracefully if the version of hdfs/yarn against
> which its being used is incompatible

> slider client should check the version of hdfs/yarn its being run against and
> then fail gracefully. Can this feature make use of some of the capability we
> are implementing for diagnostics?
