Dremio and Tableau Data Sources

Greetings all,
I am trying to get Tableau Data Sources to work smoothly with Dremio, and seem to be having some issues.
I have the Dremio 64-bit ODBC connector/driver installed, I am able to test successfully, and I am able to connect Tableau to my underlying Dremio data.
What I don’t appear to be able to do (within Tableau) is use the Tableau functionality to publish a Tableau Data Source to the Tableau Server. I get a bad connection error, which does not make sense as I am able to pull data over a live connection.
Granted, is possible this is an issue with Tableau, not with Dremio, but I am exploring the issue from both sides.

Tableau Server and Tableau Desktop v 2018.3
Dremio 2.0

Appreciate any feedback.
Many thanks,


What is the specific error you get?

Is Tableau Server installed on Linux system?

Hello Ben,
Specific error is attached.

Tableau Server is installed on a Windows system.
One additional piece, data sources publish successfully if embedded in a Tableau workbook, but I get the below error when trying to publish the data source separately.

Hi @DataSailor,

Has the Dremio Connector been installed and configured on the Tableau Server side?

Hi @ben,
Yes, Dremio connector is installed on the Tableau Server side and 64-bit ODBC connection tests successfully.

@DataSailor, in this scenario you described: “data sources publish successfully if embedded in a Tableau workbook” I believe you are using the connection and authorization associated with the Tableau Desktop installation.

The issue appears to be between the Tableau Server and Dremio. A

Are the username, password etc in the Dremio Connector different on that server than the Tableau Desktop installation?

How have you embedded credentials when you publish the workbook?

Hello @ben,
Thank you for the feedback here, and apologies for the slow reply.
My team has been able to resolve the issue, we upgraded the Tableau Server to v2019.2xx. When we did this and also upgraded our Tableau Desktop versions to the same, we found that all expected functionality with data sources, both embedded within workbooks and outside of that, worked as expected. Hopefully this will help anyone else who is experiencing similar issues.

Thank you again for your feedback, dialoging with you was helpful.
Best regards,
