> Currently, Tajo supports only equi-join, thus shuffle keys have to include
> equi-jon conditions. But it includes theta-join conditions occasionally. We
> need to update this bug, because tajo may be returned wrong row numbers.
> Actually, I found that TPC-DS Q32 had returned unexpected results by this bug.
