uncleGen updated SPARK-3376:
----------------------------
Description:
I think a memory-based shuffle can reduce some overhead of disk I/O. I just
want to know is there any plan to do something about it. Or any suggestion
about it. Base on the work (SPARK-2044), it is feasible to have several
implementations of shuffle.
