Prasanth J commented on HIVE-8322:
----------------------------------
Committed to trunk. [~vikram.dixit] This is good to have in 0.14. This is
general cleanup to Vector RS (mostly reuses code from RS) and adds additional
test.
> VectorReduceSinkOperator: ClassCastException:
> ~StandardUnionObjectInspector$StandardUnion cannot be cast to ~IntWritable
