> I don't know if this was a feature or a happy coincidence, but before
> HIVE-3230, the output of a sort merge join on two partitions would be
> bucketed, even if hive.enforce.bucketing was set to false. This could
> potentially save a reduce phase when inserting into a bucketed table.
> This would be good to have back.
