Hi, Flink will be very useful if it is embeddable in applications and can discover other nodes and cluster without relying on YARN or Hadoop. So it would be an idea to make it stand alone. Suminda -- View this message in context: http://apache-flink-incubator-mailing-list-archive.1008284.n3.n

Hey, Okay, I think this is something that I might be able to use :) The problem is that the StreamingExecutionEnvironment has nothing to do with the ExecutionEnvironment (only the name is similar) because we are completely skipping the optimizer stuff at the execution. And it seemed that the cont
