Are you using Spark 1.6 rather than Spark 2.1? I think the problem is that in spark 2.1 the transform method returns a dataset, which can be implicitly converted to a typed RDD, where as prior to that, it returns a data frame or row.

Try as a diagnostic specifying the return type of the transform function as RDD[LabeledPoint] and see if you get the same error.
