Custom Qubole Presto Connector (JDBC) - For Tableau Version 2019.1, 2019.2 and, 2019.3

Follow the instructions below to connect to QDS using the Custom Qubole Presto Connector (JDBC):

A. Download Qubole JDBC Driver

  1. Download the latest Qubole JDBC driver (version 2.3 or later). For more information, see JDBC Driver.
  2. Move the driver (jar) file to following location:
    • For Windows: C:\Program Files\Tableau\Drivers
    • For MAC: ~/Library/Tableau/Drivers
    • For Linux: /opt/tableau/tableau_driver/jdbc

B. Download Custom Qubole Presto Connector (JDBC):

Click here to download the Custom Qubole Presto Connector (JDBC).

C. Plugin the Custom Qubole Presto Connector (JDBC):

Follow the instructions below to plugin the Custom Qubole Presto Connector (JDBC):

  1. After downloading the Custom Qubole Presto Connector (JDBC), run the following command to extract plugin Qubole-Tableau-Jdbc-Plugin.zip:

    $ unzip Qubole-Tableau-Jdbc-Plugin.zip

  2. Create a directory for Tableau connectors in the following location:

    For Tableau Desktop:

    MacOS: /connector

    Windows: C:\connector

    For Tableau Server:

    Linux: /connector

    Windows: C:\connector

    Note

    The location of the connector must be in the root directory. For macOS Catalina version 10.15 or later, you are unable to write to root directory (https://support.apple.com/en-in/HT210650). Therefore, you could create a connector in any of the directories while using macOS Catalina version 10.15 or later and ensure that the user has sufficient access to read and execute files in that respective directory.

  3. Copy the qubole_jdbc directory containing your connector’s manifest.xml file in the newly created directory.

  4. Run Tableau using -DConnectPluginsPath command line argument for Tableau Desktop pointing to your connector directory, as mentioned below:

    For MAC:

    /Applications/Tableau\ Desktop\ 2019.1.app/Contents/MacOS/Tableau -DConnectPluginsPath=/connector/

    For Windows:

    cd c:\Program Files\Tableau\Tableau 2019.1\bin
tableau.exe -DConnectPluginsPath=C:\connector

  5. For Tableau Server: Run the Tableau Server Manager (TSM) with the following option to make it available for publishing:

    For Linux/Windows:

    tsm configuration set -k native_api.connect_plugins_path -v <path_to_connector> --force-keys
tsm pending-changes  apply

This operation will perform a server restart. Are you sure you wish to continue?
(y/n): y
Starting deployments asynchronous job.

You have successfully plugged in the connector.

Note

  • If you mention an incorrect <path-to-directory> which doesn’t have plugin code, you will view the following errors:

    For Tableau Desktop: Custom Qubole Presto Connector with the name “Qubole Presto” will not appear in the list of connectors when you start Tableau.

    For Tableau Server: Once you publish a report from Tableau Desktop, prompt appears with an error: “Tableau doesn’t recognize the data source type qubole_jdbc”.

    Note

    • API Token: You can find the Auth Token or Password from QDS (Control Panel > My Accounts > click Show under the API Token column and copy it). To know more, see Managing Your Accounts. If you want to add additional JDBC parameters in the EndPoint field, use semicolon (;) to separate them (Example: https://api.qubole.com;LogLevel=6;LogPath=/tmp).
    • EndPoint: Mention the EndPoint based on the region where you have the Qubole account. For more information, see Supported Qubole Endpoints on Google Cloud Platform (GCP). The EndPoint doesn’t require suffixes such as /api/xxx. For example, the EndPoint can be https://in.qubole.com.
