I am trying to execute this code to test connection to my Databricks instance. But I get

java.sql.SQLNonTransientConnectionException: [Databricks][JDBC](12330) Cannot establish a successful connection with given properties.

error. Am I missing anything in the setup?

Also, why is the driver guide (Installation and Configuration) missing in then docs folder of the driver?
