Zeppelin shows "disconnected" after the installation .

Zeppelin shows "disconnected" after the installation .

Rising Star

Followed the documentation (http://hortonworks.com/hadoop-tutorial/apache-zeppelin/) to install Zepplin on HDP 2.3.2 . After the install , I see "disconnect" message on the zeppelin home page . One of my colleague connects to the same server through a virtual machine (xendesktop) he is able to work on zeppline fine .

I have tried multiple browser's as well with same result.

my view of zeppline's instance:

my co-worker's view of the same zepplin's instance:

2184-zeppelin-2.png

You may have to restart Zeppelin to correct this. Refresh may work but restart will fix it

Please check zeppelin logs. I wonder if something is blocking it. Firewall or Antivirus ..

@Jagdish Saripella

One other thought - assuming you're using the sandbox, do you have an entry for "sandbox.hortonworks.com" in your /etc/hosts file that points to the sandbox IP address? I've seen Zeppelin not want to connect if you are using the sandbox via its IP address rather than "sandbox.hortonworks.com".
