Anyone else have feedback on this? If not I'll start a vote next week.

Hi,
+1 on the idea.
Having a stable release branch with ongoing fixes where we do not drop
major features would be good all around.
It lets us accelerate the pace of development, drop major features or
rewrite them entirely without dragging everyone else kicking & screaming
into that release.
Cheers,
Gopal

That sounds like a good idea.
Some features could be back ported to branch-1 if viable, but at least new
stuff would not be burdened by Hadoop 1/MR code paths.
Probably also a good place to enable vectorization and other perf features
by default while we make alpha releases.
+1

There is a lot of forward-looking work going on in various branches of
Hive: LLAP, the HBase metastore, and the work to drop the CLI. It
would be good to have a way to release this code to users so that they
can experiment with it. Releasing it will also provide feedback to
developers.
At the same time there are discussions on whether to keep supporting
Hadoop-1. The burden of supporting older, less used functionality
such as Hadoop-1 is becoming ever harder as many new features are added.
I propose that the best way to deal with this would be to make a
branch-1. We could continue to make new feature releases off of this
branch (1.3, 1.4, etc.). This branch would not drop old
functionality. This provides stability and continuity for users and
developers.
We could then merge these new features branches (LLAP, HBase
metastore, CLI drop) into the trunk, as well as turn on by default
newer features such as the vectorization and ACID. We could also drop
older, less used features such as support for Hadoop-1 and MapReduce.
It will be a while before we are ready to make stable, production
ready releases of this code. But we could start making alpha quality
releases soon. We would call these releases 2.x, to stress the
non-backward compatible changes such as dropping Hadoop-1. This will
give users a chance to play with the new code and developers a chance
to get feedback.
Thoughts?
