Description

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.
