mgaido91 commented on issue #22957: [SPARK-25951][SQL] Ignore aliases for distributions and orderings URL: https://github.com/apache/spark/pull/22957#issuecomment-461328814 @HeartSaVioR thanks for pointing that out! Yes, that fix is similar to this, the main difference between these 2 PRs is that this one handles also the case when we have `select a as b, a, ...` and then we have the partitioning on `a`, while #17400 doesn't (and hence may introduce a regression). Let me cc @maropu too here, since he worked on this and may have comments/suggestion or he can update his PR to handle that case and we can focus on that PR.
