Amazon Athena Connector

This node creates a connection to Amazon Athena using the native Amazon Athena JDBC driver. You need to provide the server's hostname (or IP address) and the port. Login credentials are taken from the connected Amazon Authentication connection.

Due to license restriction you need to download the Athena JDBC driver from Amazon and register it yourself. To download the driver please click here and download the latest version of the JDBC driver without the AWS SDK e.g. AthenaJDBC42-2.0.35.1001.jar. Once downloaded register the driver via the KNIME preference page with athena as database type as described in the Register your own JDBC drivers section of the KNIME Database Extension Guide.

For more information about Amazon Athena in general visit Amazon Athena and also the AWS Forums.
