This article describes how to connect Tableau to Qubole Presto and set up the data source.
Before you begin, gather this connection information:
- End Point- end point URL based on the region where you have the Qubole account
- Bucket Region
- For AWS - the region of S3 bucket that corresponds to your default storage location
- For Azure - keep the Bucket Region empty
- Catalog name ('hive' is the default)
- Cluster label
- Password (API token)
- (Optional) Initial SQL statement to run every time Tableau connects
This connector requires a driver to talk to the database. You might already have the required driver installed on your computer. If the driver is not installed on your computer, Tableau displays a message in the connection dialog box with a link to the Driver Download page where you can find driver links and installation instructions.
Start Tableau and under Connect, select Qubole Presto. For a complete list of data connections, select More under To a Server. Then do the following:
- Enter the End Point;Bucket Region.
- Enter the Catalog name.
- Enter the Cluster Label.
- Enter the Password, which is an API token.
- (Optional) Select Initial SQL to specify a SQL command to run at the beginning of every connection, such as when you open the workbook, refresh an extract, sign in to Tableau Server, or publish to Tableau Server. For more information, see Run Initial SQL.
Select Sign In.
If Tableau can't make the connection, verify that your credentials are correct. If you still can't connect, your computer is having trouble locating the server. Contact your network administrator or database administrator.
On the data source page, do the following:
(Optional) Select the default data source name at the top of the page, and then enter a unique data source name for use in Tableau. For example, use a data source naming convention that helps other users of the data source figure out which data source to connect to.
- Under Schema, select a schema or use the text box to search for a schema by name.
- Under Table, select a table or use the text box to search for a table by name.
Drag the table to the canvas, and then select the sheet tab to start your analysis.
Use custom SQL to connect to a specific query rather than the entire data source. For more information, see Connect to a Custom SQL Query.
If you use Tableau Desktop on a Mac, when you enter the server name to connect, use a fully qualified domain name, such as mydb.test.ourdomain.lan, instead of a relative domain name, such as mydb or mydb.test.
Alternatively, you can add the domain to the list of Search Domains for the Mac computer so that when you connect, you need to provide only the server name. To update the list of Search Domains, go to System Preferences > Network > Advanced, and then open the DNS tab.
