Subject [jira] [Commented] (HIVE-8732) ORC string statistics are not merged correctly
Date Wed, 05 Nov 2014 01:13:25 GMT

Dain Sundstrom commented on HIVE-8732:
--------------------------------------

The test cover a.merge(b) where is wider, but not b.merge(a).  I'd test both directions to
make sure someone doesn't introduce the opposite bug.
