    It won't satisfy my need.
    
    You may understand my concerns when you start dockerizing Zeppelin.
    
    And these days, I encounter another dockerization problem. If I put 
interpreter and server processes all in one container, the interpreter process 
will run out of memory. My final solution is deploying interpreters elsewhere.
