Gopal V commented on HIVE-9937:
-------------------------------
[~mmccline]: Pretty impressive performance difference for a shuffle-heavy
group-by is almost ~3x cpu savings.
But there are some off-by-one errors somewhere, the results out of a few keys
seem incorrect in the smaller test runs. Trying to produce a narrower test-case.
