Example 11 with MembershipListener

use of com.hazelcast.core.MembershipListener in project hazelcast by hazelcast.

the class MemberAttributeTest method testRemoveAttributes.

@Test(timeout = 120000)
public void testRemoveAttributes() throws Exception {
    TestHazelcastInstanceFactory factory = createHazelcastInstanceFactory(2);
    HazelcastInstance h1 = factory.newHazelcastInstance();
    Member m1 = h1.getCluster().getLocalMember();
    m1.setIntAttribute("Test", 123);
    HazelcastInstance h2 = factory.newHazelcastInstance();
    assertEquals(2, h2.getCluster().getMembers().size());
    Member member = null;
    for (Member m : h2.getCluster().getMembers()) {
        if (m == h2.getCluster().getLocalMember())
            continue;
        member = m;
    }
    assertNotNull(member);
    assertEquals(m1, member);
    assertNotNull(member.getIntAttribute("Test"));
    assertEquals(123, (int) member.getIntAttribute("Test"));
    final CountDownLatch latch = new CountDownLatch(2);
    final MembershipListener listener = new LatchMembershipListener(latch);
    h2.getCluster().addMembershipListener(listener);
    h1.getCluster().addMembershipListener(listener);
    m1.removeAttribute("Test");
    // Force sleep to distribute value
    assertOpenEventually(latch);
    assertNull(member.getIntAttribute("Test"));
    h1.shutdown();
    h2.shutdown();
}
