yes, this supports my theory: both the ResourceManager and the TaskManager instances are trying to reconnect to the old JobManager to re-establish a link in case of temporary failures. * In the best case, the connection is re-established and everything continues. * Since your failure is permanent, this is not the case and after some retries, Flink also thinks that ;) We can't really avoid the warnings though, even in a HA setup, since the administrator might want to know what is happening and what Flink is doing under the hood.
Everything's fine then.
