Tableau Hyper Connector for Data Prep

User Persona: Data Prep User, Data Prep Admin, or Data Source Admin


This document covers all configuration fields available during connector setup. Some fields may have already been filled out by your Administrator at an earlier step of configuration and may not be visible to you. For more information on Data Prep's connector framework, see Data Prep Connector setup. Also, your Admin may have named this connector something else in the list of Data Sources.

Configuring Data Prep

This connector allows you to connect to Tableau as an export destination. The following fields are used to define the connection parameters.


  • Name: Name of the data source as it will appear to users in the UI.
  • Description: Description of the data source as it will appear to users in the UI.


You can connect Data Prep to multiple Tableau accounts. Using a descriptive name can be a big help to users in identifying the appropriate data source. If you are a Data Prep SaaS customer, inform Data Prep DevOps how you would like this set.

Tableau Configuration

  • Tableau Server URL: An http or https URL where the Tableau Server is running. Include port if necessary. For Tableau Online, the URL must contain the pod name, such as 10az, 10ay, or us-east-1.
  • Site: Tableau site in which Data Prep will publish a data source.
  • Project: Tableau project in which Data Prep will publish a data source.
  • Overwrite Tableau Data Source: Overwrite a data source that has the same name, if one already exists.

Tableau Credentials

  • Username: Username or email address for authenticating with Tableau.
  • Password: Password for authenticating with Tableau.

Web Proxy

If you connect to Tableau through a proxy server, these fields define the proxy details.

  • Web Proxy: 'None' if no proxy is required or 'Proxied' if the connection to the Tableau REST Endpoint should be made via a proxy server. If a web proxy server is required, the following fields are required to enable a proxied connection.
  • Proxy host: The host name or IP address of the web proxy server.
  • Proxy port: The port on the proxy server for Data Source.
  • Proxy username: The username for the proxy server.
  • Proxy password: The password for the proxy server. Leave username & password blank for an unauthenticated proxy connection.

Technical Specs

Deployment Scenarios

The Tableau Hyper connector writes .hyper files using native libraries from the Tableau SDK. There are two supported deployment scenarios that allow you to use these native libraries:

  1. Use the native libraries that are bundled in the connector. This is the recommended approach.
  2. Install the Tableau SDK on the host system and remove the native libraries that are extracted from the connector zip.

If you need additional information or help installing the SDK for the Tableau Hyper Connector, please reach out to your Customer Success representative.

FAQ/Troubleshooting/Common Issues

Why are there two Tableau Connectors and what’s the difference?

Tableau “.tde” is an older extract type and was implemented with version 1.0 of Tableau’s extract API. The Tableau “.hyper” Connector is newer and is based on version 2.0 of Tableau’s extract API. We built the “.hyper” Connector as a net-new Connector so both Connectors could coexist in an account enabling customers who have many versions of Tableau running to choose the best Connector for each instance of Tableau.

Why can't my peer certificate be authenticated?

SSL communication between servers requires an identification method and something that verifies the identity assertion. Keystores (for example, jks) contain certificates and/or private keys that hold the identity assertion used when communicating with other servers. Truststores (for example, cacerts) are used when communicating with other servers to confirm it's safe to establish a connection.

If your Data Prep truststores do not have the necessary CA certificates to validate those that DataRobot receives from server connections, you may receive the following error:

To resolve this error, update the Data Prep truststore for HTTPS connections over SSL. Use the tabs below to update the Data Prep truststore for your connection type:

Connections such as Tableau will use web-based rather than Java-based connections. Therefore, use the Linux-based CA-certificates truststore.

To update this truststore, do the following:

  1. If dynamic CA isn’t enabled yet, enable it: sudo update-ca-trust force-enable.

  2. Add your root CA and any intermediate certs to /etc/pki/ca-trust/source/anchors/.

  3. Add the certs to the truststore: sudo update-ca-trust extract.

Connections such as JDBC will be Java-based and use the JKS truststore. By default, Data Prep points to its own truststore in /usr/local/paxata/server/config/



Verify this truststore before proceeding.

To use the cacerts truststore:

  1. Add a root CA and intermediate certificates to the cacerts truststore.

    sudo keytool -importcert -alias <app>_rootca -file <app>_rootca.crt -keystore /usr/lib/jvm/java-X.X.X-openjdk/jre/lib/security/cacerts
    Password: changeit
  2. Create the OBF obfuscated password for the cacerts truststore. This assumes the password for cacerts is the default changeit.

    java -cp <path to jetty-util>/jetty-util-X.X.X.vXXXXX.jar changeit
  3. Edit /usr/local/paxata/server/config/ to use the cacerts truststore.

  4. Restart the Data Prep (Paxata) core server: sudo systemctl restart paxata-server.
