Github user MasterDDT commented on the issue: https://github.com/apache/spark/pull/14092 cc @JoshRosen @rxin I wasn't sure if the right fix here is that `Expression` should override `equals` and use `semanticEquals`, that would be a bigger change but I think would work. Also I noticed the `EquivalentExpressions` class but that seemed like it was only for codegen.
