Jitendra Nath Pandey commented on HIVE-4599:
--------------------------------------------
I will recommend putting in VectorReduceSinkOperator, because that will make
vectorized map side and non-vectorize reduce side work together for non-GBy
queries too.
> VectorGroupByOperator steals the non-vectorized children and crashes query if
> vectorization fails
