Review comment:
You are right. Looks like I've tested on v2.4.0 because my SPARK_HOME
targeted to the old repo, and the logic was changed towards to exclude
duplicates in https://github.com/apache/spark/pull/23124 .
Now I'm checking on the latest master and have the same results as yours.
Thank you!
