--------------------------------------

             Summary: Host must be manually added to /etc/hosts, or else 
Zeppelin won't load
                 Key: ZEPPELIN-2883
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-2883
             Project: Zeppelin
          Issue Type: Bug
          Components: Core
    Affects Versions: 0.7.2
         Environment: Mac OS X
            Reporter: Ken Williams


I downloaded a fresh {{zeppelin-0.7.2-bin-all}} and started it with 
{{./bin/zeppelin-daemon.sh start}}.  Visiting http://localhost:8080, I get the 
stack trace shown below.

If I add {{127.0.0.1   Nerb.local}} to my {{/etc/hosts}} file, I can load 
Zeppelin properly.

I don't think the process should care what the hostname of the client is.
