Example 31 with ICountDownLatch

use of com.hazelcast.cp.ICountDownLatch in project hazelcast by hazelcast.

the class ScheduledExecutorServiceSlowTest method cancelUninterruptedTask_waitUntilRunCompleted_killMember_checkStatusIsCancelled.

@Test
public void cancelUninterruptedTask_waitUntilRunCompleted_killMember_checkStatusIsCancelled() throws Exception {
    HazelcastInstance[] instances = createClusterWithCount(2);
    String key = generateKeyOwnedBy(instances[1]);
    String runFinishedLatchName = "runFinishedLatch";
    ICountDownLatch latch = instances[0].getCPSubsystem().getCountDownLatch(runFinishedLatchName);
    latch.trySetCount(1);
    IScheduledExecutorService executorService = getScheduledExecutor(instances, "s");
    IScheduledFuture future = executorService.scheduleOnKeyOwnerAtFixedRate(new HotLoopBusyTask(runFinishedLatchName), key, 0, 1, SECONDS);
    assertFalse(future.isCancelled());
    assertFalse(future.isDone());
    future.cancel(false);
    assertTrue(future.isCancelled());
    assertTrue(future.isDone());
    // wait till the task is actually done, since even though we cancelled the task is current task is still running
    latch.await(60, SECONDS);
    // make sure SyncState goes through
    sleepSeconds(10);
    instances[1].getLifecycleService().terminate();
    // check once more that the task status is consistent
    assertTrue(future.isCancelled());
    assertTrue(future.isDone());
