Github user doanduyhai commented on the pull request: https://github.com/apache/incubator-zeppelin/pull/746#issuecomment-196040202 @felixcheung I'm still waiting for someone to reply me on my question: > By the way, for the existing asynchronous API, I don't think returning OK in all cases is correct. Since the execution of the paragraph is asynchronous and we don't wait for it to return the result to the client, how can we know if the execution has been successful or not ? How can we decide if we should return OK or INTERNAL_SERVER_ERROR ? Or do you think we can just let it as it is and create the new API ?
