public class MasterRoutePolicy
extends org.apache.camel.support.RoutePolicySupport
implements org.apache.camel.CamelContextAware

RoutePolicy to run the route in master/slave mode.

Important: Make sure to set the route to autoStartup=false as the route lifecycle is controlled by this route policy which will start/stop the route accordingly to being the master in the zookeeper cluster group.
