   > It fix by #32947 and the code related to DPP ,in spark master/3.2 the sql will be translated to normal join, instead of DPP. And, The Error is more like [SPARK-29239](https://github.com/apache/spark/pull/25925),in spark master/3.2 the skip function in addExprTree should exits same question, but the demo sql i pasted does not trigger it.
   
   So I think we should also find out which pr it can't be translated to DPP?  And backport to branch-3.1. Then we can fix current pr's issue in both master/3.2/3.1. WDYT? @LuciferYang @cloud-fan
