Ashutosh Chauhan commented on HIVE-5149:
----------------------------------------
Thanks, Yin for working on this! Can you add a test case which exposes this
bug. If I am reading it right, following query will expose it:
{code}
SELECT key, COUNT( * )
FROM
(
SELECT key, value, COUNT( * )
FROM src
GROUP BY key, value
) a
GROUP BY key;
{code}
> ReduceSinkDeDuplication can pick the wrong partitioning columns
