Hi Guys,

I am new to Zeppelin, after building the codes successfully and running hte daemon, i opened http://localhost:8080, i can't create any notebook and i am getting a notification "disconnected". Any idea on this.

Thanks.

Hi, 

Could you check if port 8081 is also accessible from your browser?

Because Zeppelin uses not only 8080 but also 8081 for web socket connection.

If you change the port number, for example 9090, web socket port will be 9091.

Let me know if it does not work even if you have access to 8081.

Best,

moon

Hi, Ebot

Appreciated for the interest.

This link can help http://zeppelin-project.org/docs/development/howtocontribute.html

Anytime you want, you can create any issue in JIRA, any pull request in our github repository.

I think sharing your feedback and idea in this mailing list can be good starting point. That's already big contribution, too 

Best,

moon

Hi, I'm running Zeppelin on a Docker container, so I my problems shouldn't be related to port issues. However, I'm also seeing
"disconnected" on the top right corner and I get this message when I run it:
