Reviewing the instructions from Hortonworks that are linked above I notice that they are using Tableau Desktop 10.2. I am not seeing anything in the release notes to indicate that the two versions would handle the connection differently. But it might be worth attempting to mirror the instructions to eliminate any possibilities. If Tableau Desktop 10.2 returns a similar error we know that there is something else causing the error to be returned other than Tableau Desktop.
I am also including several resources for the ODBC connection below. Sometimes for connections that are to slightly more customized data sources the ODBC connection can be useful.
Hope this helps!
