If the Hive server is set to use 'None' as the authentication, then the corresponding Hive driver authentication mechanism is 'Username'. To successfully connect, in the TIBCO Spotfire Hortonworks connection dialog, select 'Username' as the authentication method instead of 'No Authentication' and leave the username blank.
Note: The 'No Authentication' option in the TIBCO Spotfire Hortonworks connection dialog should be selected when the property 'hive.server2.authentication' is set to NOSASL
