Apache Spark SQL Connection¶

The Apache Spark SQL connection type enables connection to Apache Spark via the spark-sql command.

Default Connection IDs¶

Configuring the Connection¶

Host (required): The host to connect to, it can be local, yarn or an URL.
Port (optional): Specify the port in case of host be an URL.

Warning

Make sure you trust your users with the ability to configure the host settings as it may enable the connection to establish communication with external servers. It’s crucial to understand that directing the connection towards a malicious server can lead to significant security vulnerabilities, including the risk of encountering Remote Code Execution (RCE) attacks.
