> Separated a 2nd issue -- wrong result -- found by [~thiruvel] in HIVE-8417 from 1st issue (IndexOutOfBoundsException due to scratch columns in reduce-side).
> Interesting to note that in HIVE-8461 we converted Vectorization to use HiveDecimal instead of Decimal128, yet the rounding problem still occurs...
