Hi: I'm running the HDP sandbox version 2.5 (docker, on a remote LXC) and can run zeppelin through port 9995 (as anonymous), but not through ambari (server not found). There are no alerts in ambari for zeppelin. I checked the zeppelin logs and at first there was nothing suspicious. Based on previous posts, I tried looking for empty notebooks. I tried stopping and restarting zeppelin. No change. I'm definitely not experienced, so am banging my way through this. Now there is an error in the zeppelin logs but since behavior did not change, I didn't dig into this too much: ERROR [2016-10-14 22:46:57,143] ({main} Interpreter.java[register]:315) - Static initialization is deprecated. You should change it to use interpreter-setting.json in your jar or interpreter/{interpreter}/interpreter-setting.json ... View more
