> After [SPARK-12183|https://issues.apache.org/jira/browse/SPARK-12183], some mllib tree internal helper classes are no longer used at all. Also, the private helper classes internal to spark tree training can be ported very easily to spark.ML without affecting APIs. This is the "low hanging fruit" for porting tree internals to spark.ML, and will make the other migrations more tractable.
