Jacek Laskowski commented on SPARK-14500:
-----------------------------------------
What a nice surprise! Just yesterday faced the very exact problem of converting
Datasets to DataFrames due to the "incompatibility" and was wondering whether I
was doing something wrong myself. Thanks [~mengxr]!
> Accept Dataset[_] instead of DataFrame in MLlib APIs

> In Spark 2.0, `DataFrame` is an alias of `Dataset[Row]`. MLlib API actually
> works for other types of `Dataset`, so we should accept `Dataset[_]` instead.
> It maps to `Dataset<?>` in Java. This is a source compatible change.
