> Seeing an issue when dynamic sort optimization is enabled while doing an insert into
bucketed table. We seem to be flipping the negative sign on the hashcode instead of taking
the complement of it for routing the data correctly. This results in correctness issues in
bucket map joins in hive on tez when the hash code goes negative.
