Subject Re: [DISCUSS] hbase-spark module in branch-1 and branch-2
Date Wed, 18 Jan 2017 20:30:30 GMT
I don't doubt that downstream users could "try out" our integration
using what currently exists in the branch-2. However, we already had
community consensus on what is necessary for our downstream folks to
have a good experience with a ready-for-production feature. I don't
see why we should subject them to a lower bar in a branch-2 release
than we would have in a branch-1 release just because we're starting
up a new major version.

The work in HBASE-16179 is certainly a blocker given the rising
popularity of Spark 2.0 (thanks Ted for getting that work under way, I
hope we get sufficient review bandwidth to get it finished), but it's not
everything; e.g. we don't have regression checks in place for the
things that show up in our docs.
