Robert Joseph Evans commented on HADOOP-8054:
---------------------------------------------
Amareshwari said the patch works. The tests look good, and the patch looks
good. +1
Because this breaks HIVE and is a regression I would like to see this go into
0.23.1. I will put it into trunk and 0.23.2, but please consider this for
0.23.1.
