Thanks, Nico.
I look again at flink-examples- streaming_2.10-1.4-SNAPSHOT.jar, and it indeed contains both. Originally I was looking at each self-contained jars as I used them as examples to create and run my own streaming program. They only contain java compiled class, if I am not mistaken. Let me try to create a scala example with similar build procedure. Thanks!
