Subject Re: DISCUSS: Hadoop Compatability Guidelines
Date Tue, 05 Sep 2017 18:04:12 GMT
Thanks for starting this Daniel.

I think we should also add a section for store compatibility (all state
stores including RM, NM, Federation etc.). Essentially an explicit policy
detailing when is it ok to change the major and minor versions and how it
should relate to the hadoop release version.
Thoughts ?

Cheers
-Arun
