Github user StephanEwen commented on the pull request: https://github.com/apache/flink/pull/996#issuecomment-129560955 Since Kafka is Apache, copying should be okay. It is good style, though, to add to every copied file a note of origin. And this is a temporary solution anyways, since we can get rid of most of the copied files as soon as the new Kafka release is properly out.
