Link to create new notebook doesnt work - disconnected status

[matt Lieber]

hi,

I built everything successfully and can start the UI.

But clicking on 'create new notebook' doesnt work/result in anything. My status is disconnected. 

This is on Ubuntu.

netstat shows that 8081 is only used by Zeppelin (i.e. if i stop Zeppelin, 8081 is not used anymore).

I also tried changing ports by having:

in conf/zeppelin-site.xml:

<property>  <name>zeppelin.server.port</name>

  <value>8090</value>

</property>

and in conf/zeppelin-env.sh:

ZEPPELIN_PORT=8090

But then i cannot load the app, when i go to localhost:8090.

Any idea what could be going on ? 

Also the log doesnt help, nothing is stated there.

Thanks!

Matt
