----------------------------------------------------------------
"Isn't there still a somewhat hidden Scala dependency in flink-streaming-java,
because it relies on the KryoSerializer stuff in flink-scala? 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).
