Github user yanboliang commented on the issue: https://github.com/apache/spark/pull/12790 @MLnick Thanks for clarification. Then I think current fix is OK, since Scala is strongly typed, we can regard ```Array()``` or ```Array.empty``` as wrong input and throw exception. It's not nece

Github user MLnick commented on the issue: https://github.com/apache/spark/pull/12790 Actually the behavior in Scala is consistent - passing in `Array()` or `Array.empty()` you are passing in `Array[Nothing]` so that is why there is a `ClassCastException`. Passing in an empty

Github user yanboliang commented on the issue: https://github.com/apache/spark/pull/12790 @BryanCutler @MechCoder The current fix of removing the default value for the ```stages``` param is OK for me. But we also should discuss the behavior of ```stages=[]``` which is inconsistent bet
