Carl Steinbach commented on HIVE-3072:
--------------------------------------
If this feature requires metastore changes then I'd like to request that the
first patch contain only changes to the metastore schema and metastore Thrift
API. I would also prefer that the DML and DDL changes go in as a single patch
since it a) prevents half-implemented features from showing up in releases and
b) demonstrates that the feature actually works.
