RJ Nowling commented on ZEPPELIN-10:
------------------------------------

[~bzz] I think that Zeppelin's usage of 2 ports causes multiple problems with 
port forwarding.  [~epakhomov]'s use case (wanting to be able to use random 
ports) is one example of this being a problem.  If Zeppelin is ever deployed on 
kubernetes, the port-forwarding issues will be a huge stumbling block.  Another 
is related to authentication using a reverse proxy such as nginx.  

I suggest we either change the JIRA to document the port-forwarding issues or 
create a new JIRA.

> Zeppelin put UI on ZEPPELIN_PORT and web_socket on ZEPPELIN_PORT+1. When you 
> run docker with standart -P 
> argument(https://docs.docker.com/userguide/usingdocker/) it maps these ports 
> to some other ports. For example you set  ZEPPELIN_PORT=8080 and export 8080, 
> 8081. But in reality it would be some other ports(49159, 49160). And Zeppelin 
> don't know anything about them. And UI doesn't work properly.
