    * [ZEPPELIN-1212](https://issues.apache.org/jira/browse/ZEPPELIN-1212)
    
    ### How should this be tested?
    In JDBC interpreter setting add following properties
    
     - zeppelin.jdbc.auth.type = KERBEROS
     - zeppelin.jdbc.principal = principal value
     - zeppelin.jdbc.keytab.location = keytab location
     - enable shiro authentication via shiro.ini
    
    Now try and run any of hive's query (say show tables) it should return with 
valid results/errors depending on user permission.
