> aggregateResultType does not seem necessary for
> streaming.api.datastream.aggregate. We will anyway not serialize the
> aggregateResult between aggregate and window function. Aggregate function
> itself provides a function to getResult(), window function here should just
> emit the same results as aggregate output. So aggregateResultType should be
> same as resultType. I think we can safely remove aggregateResultType, thereby
> user will not have to provide two same types for the
> streaming.api.datastream.aggregate.
> [~StephanEwen], what do you think?
