Team,
I am trying to get IntelliJ working with predictionIO. I have been
following this turorial and am getting close to getting the PIO Train to
work but it looks like it is failing as it goes to persist the model. This
in turn seems to be causing the `pio deploy` in intelliJ to fail as well.
What I really am trying to do is get into an environment where I can test
the code and view the dataframes as they are being created. I am new to
PredictionIO and Scala. I am trying to find a way to view the contents of class
TrainingData(
val ratings: RDD[Rating]
) extends Serializable {
override def toString = {
s"ratings: [${ratings.count()}] (${ratings.take(2).toList}...)"
}
}
