Hi this uses the java Services framework in order to load a defined class at runtime based on the users configuration. I'm not too familiar with Scala but the java documentation for ServiceLoader is here: https://docs.oracle.com/javase/9/docs/api/java/util/ServiceLoader.html. Depending on your security or other settings there is a possibility for issues finding the class. For example in Presto Phoenix Connector I believe the following change had to be made in order to get the presto connector run. https://github.com/prestosql/presto/commit/30539e200ad0c4809afd2a9b178998829b548e2e
