> SPARK-8317 changed the SQL Exchange operator so that it no longer pushed sorting into Spark's shuffle layer, a change which allowed more efficient SQL-specific sorters to be used.
> There's still some leftover cleanup from that patch which needs to be performed: Exchange's constructor should no longer accept a {{newOrdering}} since it's no longer used.
