Or are these only required for Scala applications?" ==> We discussed that offline between [~chesnay], me, and others, and indeed, there is a physical dependency. But it is possible to decouple that, and instantiate Kryo in the absence of the Scala modules with a smaller set of default serializers (not including the Scala serializers). was (Author: stephanewen): [~chesnay] "Isn't there still a somewhat hidden Scala dependency in flink-streaming-java, because it relies on the KryoSerializer stuff in flink-scala?
