Using Tableau to Access HetuEngine

Use Tableau Desktop 2022.2 as an example to describe how to access HetuEngine.

Tableau Desktop has been installed.
The JDBC JAR file has been obtained. For details, see 1.
A human-machine user, for example, hetu_user, has been created in the cluster. For details, see Creating a HetuEngine User. For clusters with Ranger authentication enabled, the Ranger permission must be added to user 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 HetuEngine Compute Instances.

Place the obtained JAR file to the Tableau installation directory, for example, C:\Program Files\Tableau\Drivers.
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 in the HSBroker mode. For details about the URL format, see Table 1.
After the login is successful, drag the data table to be operated to the operation window on the right and refresh data.
