Description

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...
