What changes were proposed in this pull request?
Changes in how py4j pyspark API works. It looks like there is a problem with
mixins.scalawhen you are trying to work with them from Java (or py4j).This PR changes how it is called from py4j. Instead of chaining calls, it calls methods one by one because they have side-effects internally any way.
Why are the changes needed?
