Critical Description
spark.ml.LDAModel exposes dependencies on spark.mllib in 2 methods, but it should not:
- def oldLocalModel: OldLocalLDAModel
- def getModel: OldLDAModel
This task is to deprecate those methods. I recommend creating private[ml] versions of the methods which are used internally in order to avoid deprecation warnings.
Setting target for 2.2, but I'm OK with getting it into 2.1 if we have time.
