Hi Alvaro I suspect YARN is not supporting to register any custom listeners from user end (for any events). Through the REST api's, you could query and try to get the STATE of the application (http://{ip:port}/ws/v1/cluster/apps/{appid}) given the app id. If the app state is RUNNING, you can consider the application has started.
