Gang Tim Liu commented on HIVE-3072:
------------------------------------
We rethink "release approach". We can deliver DDL and DML as separate patches
or a single patch. Either has pros and cons. not perfect. Separate patch
approach can make release more manageable. A single patch makes release make
more sense because with DDL but no DML you can't experience list bucketing.
We have to pick up one. We choose a single patch approach. It reduces overhead
of multiple-patch release, gives community more time to review proposal and
reserves room for us to adjust according to proposal review.
I will call proposal review again today.
