Gschiavon commented on issue #25728: [SPARK-29020][WIP][SQL] Improving array_sort behaviour URL: https://github.com/apache/spark/pull/25728#issuecomment-532071387 The problem here is the naming of the HOF array_sort. In the `registry` we have this : ` expression[ArraySort]("array_sort")` `expression[ArraySorting]("array_sort")` I think names should be different, for example, this is array_zip (arrays_zip in the code) ` expression[ArraysZip]("arrays_zip")` ` expression[ZipWith]("zip_with")` Maybe they don't do exactly the same, I'm not sure. But other examples with the Array HOF would be: ` expression[ArrayFilter]("filter"), expression[ArrayExists]("exists"), expression[ArrayForAll]("forall") `
