Using Tableau to Access HetuEngine

Prerequisites

• Tableau Desktop has been installed.
• The JDBC JAR file has been obtained. For details, see 1.
• You have created a human-machine user, for example, hetu_user, in the cluster. For details, see Creating a HetuEngine User. For clusters with Ranger authentication enabled, you need to grant the Ranger permission to hetu_user based on service requirements. For details, see Adding a Ranger Access Permission Policy for HetuEngine.
• A compute instance has been created and is running properly. For details, see Creating a HetuEngine Compute Instance.

Procedure

1. Place the obtained JAR file to the Tableau installation directory, for example, C:\Program Files\Tableau\Drivers.
2. Open Tableau, choose To a Server > Other Databases (JDBC), enter the URL and the username and password of the created human-machine user, and click Sign In. HetuEngine is accessible either with HSFabric or HSBroker. For details about the URL format, see Table 1.

   

3. After the login is successful, drag the desired data table to the operation window on the right and refresh data.
