Example 1 with ServiceSelector

use of com.facebook.airlift.discovery.client.ServiceSelector in project presto by prestodb.

the class TestHeartbeatFailureDetector method testExcludesCurrentNode.

@Test
public void testExcludesCurrentNode() throws Exception {
    Bootstrap app = new Bootstrap(new TestingNodeModule(), new TestingJmxModule(), new TestingDiscoveryModule(), new TestingHttpServerModule(), new TraceTokenModule(), new JsonModule(), new JaxrsModule(true), new FailureDetectorModule(), new Module() {

        @Override

            configBinder(binder).bindConfig(InternalCommunicationConfig.class);
            configBinder(binder).bindConfig(QueryManagerConfig.class);
            discoveryBinder(binder).bindSelector("presto");
            discoveryBinder(binder).bindHttpAnnouncement("presto");
            // Jersey with jetty 9 requires at least one resource
            // todo add a dummy resource to airlift jaxrs in this case
            jaxrsBinder(binder).bind(FooResource.class);
        }
    });
    Injector injector = app.doNotInitializeLogging().quiet().initialize();
    ServiceSelector selector = injector.getInstance(Key.get(ServiceSelector.class, serviceType("presto")));
    assertEquals(selector.selectAllServices().size(), 1);
    HeartbeatFailureDetector detector = injector.getInstance(HeartbeatFailureDetector.class);
    detector.updateMonitoredServices();
