maropu edited a comment on issue #27233: [SPARK-29701][SQL] Correct behaviours of group analytical queries when empty input given URL: https://github.com/apache/spark/pull/27233#issuecomment-575498955 In my first try, I did so (I modified code in `ResolveGroupingAnalytics`), but I couldn't fix the resolution code cleanly about [the Filter/Sort cases](https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala#L588-L602) and `ResolveAggregateFunctions`. If we should handle this case in the analyzer side, I'm ganna try again based on the approach.
