Example 1 with TestingSchedulerNGFactory

use of org.apache.flink.runtime.scheduler.TestingSchedulerNGFactory in project flink by apache.

the class JobMasterTest method testJobMasterOnlyTerminatesAfterTheSchedulerHasClosed.

@Test
public void testJobMasterOnlyTerminatesAfterTheSchedulerHasClosed() throws Exception {
    final CompletableFuture<Void> schedulerTerminationFuture = new CompletableFuture<>();
    final TestingSchedulerNG testingSchedulerNG = TestingSchedulerNG.newBuilder().setCloseAsyncSupplier(() -> schedulerTerminationFuture).build();
    final JobMaster jobMaster = new JobMasterBuilder(jobGraph, rpcService).withSlotPoolServiceSchedulerFactory(DefaultSlotPoolServiceSchedulerFactory.create(TestingSlotPoolServiceBuilder.newBuilder(), new TestingSchedulerNGFactory(testingSchedulerNG))).createJobMaster();
    jobMaster.start();
    final CompletableFuture<Void> jobMasterTerminationFuture = jobMaster.closeAsync();
    try {
        jobMasterTerminationFuture.get(10L, TimeUnit.MILLISECONDS);

    } catch (TimeoutException expected) {
    }
    schedulerTerminationFuture.complete(null);
    jobMasterTerminationFuture.get();
}

Example 2 with TestingSchedulerNGFactory

use of org.apache.flink.runtime.scheduler.TestingSchedulerNGFactory in project flink by apache.
