[~slcclimber] I think you need to call `_convert_to_vector` at https://github.com/anantasty/spark/compare/SPARK-4127#diff-66c3b8d150a095b53b5fa5cfad009717R290 . There are examples in MLlib, e.g., https://github.com/apache/spark/blob/master/python/pyspark/mllib/regression.py#L57 .
Maybe I missed some lines. But I think when you send a Vector on the Python side, you should get a vector on the Scala side. It is not necessary to go through the bytearray explicitly, for example:
