> We should add {{mapPartitionsWithIndex()}} to the Java API.
> What should the interface for this look like? We could require the user to
> pass in a {{FlatMapFunction[(Int, Iterator[T]))}}, but this requires them to
> unpack the tuple from Java. It would be nice if the UDF had a signature like
> {{f(int partition, Iterator[T] iterator)}}, but this will require defining a
> new set of {{Function}} classes.
