@wangyum I don't think this fix will solve all problems. Empty relation propagation can cause invalid plans in other ways, e.g., a `BroadcastExchangeExec` ending up as the child of a random plan node other than BHJ or BNLJ. So you can approach this problem from a different angle. Have an invalid plan checker to detect those patterns and throw a specific exception that can be caught by `AdaptiveSparkPlanExec`'s replanning method and so it can void the latest plan and keep the old valid plan in use. -- This is an automated message from the Apache Git Service.
