> Both classes org.apache.flink.streaming.api.environment.StreamExecutionEnvironment and org.apache.flink.api.java.ExecutionEnvironment have a lot in common (same methods for kryo registration, fromCollection, etc) but are not related by a java contract.
> That leads to annoying differences, for instance : StreamExecutionEnvironment.setParallelism() returns 'this' where as ExecutionEnvironment.setParallelism() has not return value.
> They have specificities, but maybe they should both implement a common Interface to make sure that the common signatures are coherent?
