The Datastax driver was updated in Horizon 32, and now requires an additional configuration directive and file. This was mentioned in the H32 release notes, but the deployment documentation does not convey its importance. The `org.opennms.newts.config.driver_settings_file` setting is mentioned in the midst of many other settings, but it's not listed as required. The Cassandra storage strategy will not work without both this setting, and a properly configured configuration file at the location specified by the setting. Customers upgrading their OpenNMS installations from pre-H32 versions, or configuring NewTS for the first time, may easily miss this and the errors produced in the OpenNMS logs do not make it obvious where the configuration error may be.
