Estimator

abstract class Estimator[A, B] extends EstimatorOperator

An estimator has a fitRDD method which takes an input and emits a Transformer

A

The type of input this estimator (and the resulting Transformer) takes

B

The output type of the Transformer this estimator produces when being fit
