did you check the option SSL when you try to connect?
Because for what I understood, the data source is using SSL security, and you try to connect pass in the connection a no SSL connection.
Thanks for the reply Paulo. But, in Tableau Desktop 9.3 version there is no SSL option on the connect screen. Only version 10.0 onwards have that option. That's the main issue here. I have to get this 9.3 to work with SSL and Hortonworks Hadoop Hive connection. Any other thoughts ?
