Description

SPARK-41471 allowed Spark to shuffle just one side and still conduct SPJ, if the other side is KeyGroupedPartitioning.  However, the support was just for a KeyGroupedPartition without any partition transform (day, year, bucket).  It will be useful to add support for partition transform as well, as there are many tables partitioned by those transforms.
