I think this is a proxy security issue, I will have to figure this out on my own unless there is some method to not use web sockets in Zeppelin.

When I run it locally I can see the full Zeppelin home page. When I run the exact same image on my EC2 instance, I can only see the top of the page, the header bar. I have tried both with Zeppelin 0.7.0 and 0.7.1. I opened the Developer Toolbar in Chrome and noticed that a websocket request is repeatedly failing. It periodically sends a websocket request to ‘https://<my_ip>/jax/input/TeX/config.js?V=2.7.0’, the initiator is vendor.ee876a1abacbe752.js:386. The status is 401, and type is websocket. From what I read, websockets communicate over port 80 and 443 as well, so I don’t understand why this is failing. My EC2 security groups permit inbound TCP traffic over port 80 and 443. Is something else required? I think network traffic is also passing through a proxy server, I’m not sure how that is configured. On a separate note: if NPM is not required, then can we please not have its stack trace in the logs? When I see that I think something is broken, but you are saying it’s not required. I attached the log file and standard output file, but I don’t think they will help solve this problem. Is there some configuration to make Zeppelin not use websockets? Or maybe any other workaround?

Can you please post a full log (*.log, *out)? Raffaele 2017-04-03 23:54 GMT+02:00 Knapp, Michael <michael.kn...@capitalone.com<mailto:michael.kn...@capitalone.com>>: Zeppelin Developers, I am struggling to get Zeppelin to work. I am running version 0.7.1 on an amazon linux EC2 instance. I used the binary package with all interpreters. I am running this as the anonymous user. Please keep in mind two things: 1. We are using proxies, so if the app must download NPM, then I will at least need to configure it to use a proxy. I saw no documentation on that on your website. 2. Depending on the amazon instance’s security groups, I may not be able to download npm packages anyways. This is why I upgraded to 0.7.1, so I will not be required to do that. When I start Zeppelin, it appears to be empty. If I click the “Notebook” drop down menu, no notebooks seem to exist, while the logs state that six of them were created for the tutorial. I see these lines in my logs: INFO [2017-04-03 21:35:34,675] ({main} Folder.java[addNote]:184) - Add note 2BWJFTXKJ to folder Zeppelin Tutorial INFO [2017-04-03 21:35:34,690] ({main} Folder.java[addNote]:184) - Add note 2C57UKYWR to folder Zeppelin Tutorial INFO [2017-04-03 21:35:34,783] ({main} Folder.java[addNote]:184) - Add note 2C35YU814 to folder Zeppelin Tutorial INFO [2017-04-03 21:35:34,799] ({main} Folder.java[addNote]:184) - Add note 2A94M5J1Z to folder Zeppelin Tutorial INFO [2017-04-03 21:35:34,814] ({main} Folder.java[addNote]:184) - Add note 2C2AUG798 to folder Zeppelin Tutorial INFO [2017-04-03 21:35:34,831] ({main} Folder.java[addNote]:184) - Add note 2BYEZ5EVK to folder Zeppelin Tutorial INFO [2017-04-03 21:35:34,832] ({main} Notebook.java[<init>]:127) - Notebook indexing started...

Looking through the logs, I see that many interpreters were registered. I see 22 interpreters in my zeppelin interpreters directory. I don’t know why none of them are options when I try to create a new note. Lastly, I tried creating a new note, but it seems like nothing happens. I give my note a name, and click Create Note, the form disappears, but I see no new lines in my logs, and from the UI “Notebook” menu, the new note is not shown. Please help, I have no idea why this is simply not working.
