This article refers to Athena specifically, but this can apply to any JDBC connector. To find instructions for resolving this issue, see the Tableau Knowledge Base article called Tableau Fails To Connect to Amazon Athena through Proxy With Error Code 37CE01A3. For example, if you select “Use the same proxy server for all protocols,” the Java Virtual Machine tries to use a SOCKS proxy. Starting with version 2019.4, when Tableau runs on Windows, it reads proxy settings by enabling the useSystemProxies option for Java.

If you are running a JDBC driver that is not Java 11 compatible, you may experience problems running Tableau. I'm seeing a “ClassNotFoundException” (or similar) message.

To isolate the Athena driver from the Postgres driver, install them in separate subdirectories:Īfter you have moved the drivers, restart Tableau. Suppose you have these libraries installed in the JDBC folder:

If you have strange errors while connecting, and you have multiple JDBC drivers installed in the JDBC drivers folder, then you can use the following steps to isolate them.
This may cause problems in unpredictable ways. If you have multiple JDBC drivers installed for Tableau, they may use different version of the same third-party library. I have multiple JDBC drivers installed for Tableau, but I'm having trouble connecting. Linux: /opt/tableau/tableau_driver/jdbcĮnsure that the driver is readable by the user running Tableau, or the Tableau service user.Windows: C:\Program Files\Tableau\Drivers.Install the driver, and any libraries it depends on, in one of the following paths: Starting with version 2020.2, all Tableau applications are bundled with the Java Runtime, so you won't have this error. See the Driver Downloads (Link opens in a new window) page for instructions on installing the correct version of Java for your connector. This sometimes happens if you are using a version of Tableau before 2020.2 or using Kerberos on Windows. Here is a list of some common problems and steps to resolution. Note: Tableau will provide reasonable levels of customer support to assist in troubleshooting connections with JDBC drivers, but can't create or customize a connector to work with a specific JDBC driver. Some JDBC drivers might not work with Tableau. Some JDBC drivers will support the full Tableau interactive experience, while others may work only for creating extracts. Tableau provides no guarantee or warranty that using the Other Databases (JDBC) connector with any particular JDBC driver or database will be able to successfully connect and query data. Tableau supports the ability to customize your JDBC data connection, which can improve the connection experience. Note: If you are using a version of Tableau Desktop before 2020.2, see the Driver Downloads (Link opens in a new window) page for instructions on installing Java. Starting with version 2020.2, all Tableau applications are bundled with the Java Runtime, so you don't have to install it separately.
JDBC requires Java, which makes it platform-independent. This includes both official named connectors, such as Athena, and generic connector for use with other JDBC-based drivers, called Other Databases (JDBC). Tableau supports JDBC (Java Database Connectivity) drivers for several connectors.
