Example 1 with ActorRef

use of akka.actor.ActorRef in project flink by apache.

the class JobClientActorTest method testConnectionTimeoutAfterJobSubmission.

/** Tests that a {@link org.apache.flink.runtime.client.JobClientActorConnectionTimeoutException}
	 * is thrown after a successful job submission if the JobManager dies.
	 *
	 * @throws Exception
	 */

Example 2 with ActorRef

use of akka.actor.ActorRef in project flink by apache.
