How to define custom keys and Partitioners?

[punit-naik]

I have a scala program in which I define custom keys and create custom partitioners. How can I do this using flambo?

Specifically I want the following code to be transformed into clojure using flambo:

case class RFMCKey(cId: String, R: Double, F: Double, M: Double, C: Double)
class RFMCPartitioner(partitions: Int) extends Partitioner {
 require(partitions >= 0, "Number of partitions ($partitions) cannot be negative.")
 override def numPartitions: Int = partitions
 override def getPartition(key: Any): Int = {
 val k = key.asInstanceOf[RFMCKey]
 k.cId.hashCode() % numPartitions
 }
}
object RFMCKey {
 implicit def orderingByIdAirportIdDelay[A <: RFMCKey] : Ordering[A] = {
    Ordering.by(k => (k.R, k.F * -1, k.M * -1, k.C * -1))
 }
}

How can I do this?

I noticed that you already posted this question to the flambo-user mailing list, which is the appropriate place rather than an issue here.
