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.

> If a hive table column has skewed keys, query performance on non-skewed key
