https://github.com/apache/spark/pull/17220
Hash-based shuffle has some problems with large number of partitions, and
part of hash-based shuffle's feature has already been incorporated into
sort-based shuffle. Spark's sort-based shuffle is not pure sort-based like MR,
it is actually a mixed pattern depends on the partition numbers.
