      Description

      Hello. I'm trying to configure zeppelin in cluster mode. 

      When I change interpreter settings they implement only on local node and  I get  error on remote node:
      ({netty-messaging-event-epoll-client-3} NettyMessagingService.java[lambda$null$20]:531) - An error occurred in a message handler: {} │
