HI Francis, thank you for your interest in using Zeppelin with AWS EMR, and please keep sharing it.
The reason you have "disconnected" state is that before https://github.com/apache/incubator-zeppelin/pull/170 as it is mentioned here https://github.com/apache/incubator-zeppelin#run Zeppelin neededs 2 open ports: 8080 for REST API and 8081 for websocket communication (both are configurable, but those are defaults) - and 'disconnected' usually means that wesocket one is not available. Can you make sure you both are accessible on your setup (i.e using nc)? I.e the link you pointed have instructions to setup both port forwarded though SSH and that is essential. Another option would be to build Zeppelin \w #140 patch and see if that solves the issue. Please, let me know if that helps! -- BR, Alexander.
