maropu commented on issue #27233: [WIP][SPARK-29701][SQL] Correct behaviours of group analytical queries when empty input given URL: https://github.com/apache/spark/pull/27233#issuecomment-576093949 @cloud-fan I'm checking that approach again; as you said above, that appraoch is more straighforward for fixing this issue. But, I need more time cuz the previous try broke the many existing tests and I gave up imidiately... @dongjoon-hyun Thanks for the comment. I don't want to block the 2.4.5 release. Do you think the release should include this fix? Yea, this is a correctness issue, but I feel its a corner case.
