> Lateral Join has no meaning without rule `RewriteLateralSubquery`. So now if we set `spark.sql.optimizer.excludedRules=org.apache.spark.sql.catalyst.optimizer.RewriteLateralSubquery`, the lateral join query will fail with:
> {code:java}
> java.lang.AssertionError: assertion failed: No plan for LateralJoin lateral-subquery#218
> {code}
