Shannon Ladymon commented on HIVE-9824:
---------------------------------------

for *hive.vectorized.execution.mapjoin.minmax.enabled* should read "max/max" or
"min/max".

> Today's VectorMapJoinOperator is a pass-through that converts each row from a
> vectorized row batch in a Java Object[] row and passes it to the
> MapJoinOperator superclass.
> This enhancement creates specialized vectorized map join operator classes
> that are optimized.
