      Description

      How to initialize state tranformation updateStateByKey?

      I have word counts from previous spark-submit run, and want to load that in next spark-submit job to start counting over that.

      One proposal is to add following argument to updateStateByKey methods.
      initial : Option [RDD [(K, S)]] = None

      This will maintain the backward compatibility as well.

      I have a working code as well.
