Matt McCline commented on HIVE-12750:
-------------------------------------
Newly added validation seems to be catching CasLongToDouble not handling nulls
correctly (vectorization_not.q, etc). Perhaps we should turn off validation to
get this wrong results issue fixed and create additional JIRAs to solve the
other issues...
> Vectorization logic not maintaining noNulls flag and isNull array properly
> causing wrong query results
