Saisai Shao commented on SPARK-5315:
------------------------------------
Another point need to be noted that the {{reduceFunc}} in reduceByWindow's
parameter is scala's Function, not the Java Function2 , even with JavaDStream
wrapped cannot solve the problem, actually the code cannot be compiled.
> reduceByWindow returns Scala DStream not JavaDStream
