Exception occurred when initializing new KNNRegression()

val knn = new KNNRegression().setTopTreeSize(df.count().toInt / 500)
.setFeaturesCol("features")
.setPredictionCol("predicted")
.setK(1)

This throws the following exception,

It's not able to load your KNN object, do you have the spark classpath pointing to your JARs?
