Tableau Desktop and Web Authoring Help

This article describes how to connect Tableau to open source Apache Impala and set up the data source.

Before you begin

Before you begin, gather this connection information:

• Name of the server that hosts the database you want to connect to and the port number

• Authentication:

  • None

  • LDAP

  • Integrated (Kerberos)

• Username and password depending on the authentication method you choose
• Transport Mode
• Database
• Thrift protocol version
• Are you connecting to an SSL server?

Driver required

This connector requires a driver to talk to the database. 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(Link opens in a new window) page where you can find driver links and installation instructions.

   1. Enter the Server name and Port.

   2. Select an Authentication method and enter a username and password if prompted.

   3. Select a Transport Mode

   4. (Optional) Enter a database to connect to.
