------------------------------------
Well, add to the mystery, when I run that query with vectorization on and on MR
(i.e. no native vector map join since we only do Tez), I get the following
exception!

> 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.
