Github user Leemoonsoo commented on the issue: https://github.com/apache/zeppelin/pull/2986 I'd like to separate Bi-directional RPC and Bi-directional network connection. Of course Bi directional RPC of course gives lots of benefits. But Bi-directional network connection requirement is not the benefit i can think of. So i was curious how we can simplify connection requirement while having benefit of bi-directional rpc capability.
