Subject [jira] [Commented] (HIVE-16659) Query plan should reflect hive.spark.use.groupby.shuffle
Date Fri, 30 Jun 2017 15:40:01 GMT


Rui Li commented on HIVE-16659:

Thanks [~libing] for working on this. Patch looks good overall. Can you create an RB for it?
And a side note is, we usually base the patch against master. If you want to develop for a
specific branch, you should name your patch accordingly (refer to this [wiki|]).

I think it's OK to remove the RepartitionShuffler, as it's effectively the same as SortByShuffler
w/o total order. [~csun], [~xuefuz] please let me know if you think otherwise.

> It's useful to show the shuffle type used in the query plan. Currently it shows "GROUP"
no matter what we set for hive.spark.use.groupby.shuffle.
