allisonwang-db opened a new pull request #30437: URL: https://github.com/apache/spark/pull/30437
Backport #30373 for branch-2.4. ### What changes were proposed in this pull request? This PR switched the order for the rule `RemoveRedundantSorts` and `EnsureRequirements` so that `EnsureRequirements` will be invoked before `RemoveRedundantSorts` to avoid IllegalArgumentException when instantiating PartitioningCollection. ### Why are the changes needed? `RemoveRedundantSorts` rule uses SparkPlan's `outputPartitioning` to check whether a sort node is redundant. Currently, it is added before `EnsureRequirements`. Since `PartitioningCollection` requires left and right partitioning to have the same number of partitions, which is not necessarily true before applying `EnsureRequirements`, the rule can fail with the following exception: ``` IllegalArgumentException: requirement failed: PartitioningCollection requires all of its partitionings have the same numPartitions. ``` ### Does this PR introduce _any_ user-facing change?
