             Summary: Create Interpreter throw a .java.net.UnknownHostException: root: root: Name or service not known
                 Key: ZEPPELIN-2401
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-2401
             Project: Zeppelin
          Issue Type: Bug
          Components: Interpreters
    Affects Versions: 0.7.1
         Environment: zeppelin 0.7.1
Centos 6.5
openjdk-1.8.0

            Reporter: Cupen Noruler
            Priority: Trivial


I meet a little problem, when I create a interpreter whether python, jdbc or others, zeppelin throw an UnknownHostException. 

My hostname was "root", so I change the hostname to 'localhost', then it works fine. I don't why is the interpreters depend on localhost ?
