public class PreferredNodeHealthStatusController
extends BaseController

This controller is used by an active health check. The purpose of this health check is to mark nodes as non-healthy if there are "more preferred" nodes available. A "more preferred" node is a main one, or (if there is no online main node) a node with "Processing user requests to modify data" responsibility. In case when there are no online preferred nodes, then any other node is considered healthy.
