class ReplicaPartitioner[T] extends Partitioner

The replica partitioner will work on an RDD which is keyed on sets of InetAddresses representing Cassandra Hosts . It will group keys which share a common IP address into partitionsPerReplicaSet Partitions.

    Given a set of endpoints, pick a random endpoint, and then a random partition owned by that endpoint.

    Given a set of endpoints, pick a random endpoint, and then a random partition owned by that endpoint. If the requested host doesn't exist chose another random host. Only uses valid hosts from the connected datacenter.
