@Christopher Brandt,
If you are using RIH, OPA is currently not supported with Databricks connector. Another way would to use OPA on top of JDBCI found this article is pretty useful: https://dbschema.com/documentation/databricks/ . I would say: Download JDBC driver for databricks and place DatabricksJDBC42.jar file in lib , on a high level we need JDBC url Driver according to databricks version in OPA lib
Also, the Reltio Connector for Databricks is in in EA and not used by everyone yet. I hope this helps.
