Liang-Chi Hsieh ae61f187aa [SPARK-22206][SQL][SPARKR] gapply in R can't work on empty grouping columns ... ## What changes were proposed in this pull request? Looks like `FlatMapGroupsInRExec.requiredChildDistribution` didn't consider empty grouping attributes. It should be a problem when running `EnsureRequirements` and `gapply` in R can't work on empty grouping columns. ## How was this patch tested? Added test. Author: Liang-Chi Hsieh <viirya@gmail.com> Closes #19436 from viirya/fix-flatmapinr-distribution.		2017-10-05 23:36:18 +09:00
