> 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.
