> 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.
