Don't know why this google group doesn't allow me to post at the end now, 
anyway, hopefully you notice my post:

I read your (@takowl and @Roland Weber) points and that could be the reason 
since I am actually doing this on a cluster which consists of 15 nodes.

However, I still do not understand:
1. I opened a session1 and edited the jupyter_notebook_config.py 
accordingly;
2. I started the jupyter service on another session2 and there it prompted 
error I posted here;

Both the two sessions are on the same host.

Now I changed my testing:
I opened session 1 and confirmed the editting
I started the jupyter service on the SAME session
I tested from session 2 and it works! I tested from workstation browser and 
it works!

However, new issue follows right after this:

When I open http://myhostname:8880
it takes me to: http://myhostname:8880/tree#notebooks, the notebook GUI is 
displayed

When I click on any item under the New menu on the right top, I get error 
of permission denied.

So what am I missing here? we do have Sentry in place, how do I set up the 
right access?

Thank you.
