Example 21 with Metadata

use of org.apache.kafka.clients.Metadata in project kafka by apache.

the class AbstractCoordinatorTest method setupCoordinator.

@Before
public void setupCoordinator() {
    this.mockTime = new MockTime();
    this.mockClient = new MockClient(mockTime);
    Metadata metadata = new Metadata();
    this.consumerClient = new ConsumerNetworkClient(mockClient, metadata, mockTime, RETRY_BACKOFF_MS, REQUEST_TIMEOUT_MS);
    Metrics metrics = new Metrics();
    Cluster cluster = TestUtils.singletonCluster("topic", 1);
    metadata.update(cluster, Collections.<String>emptySet(), mockTime.milliseconds());
    this.node = cluster.nodes().get(0);
    mockClient.setNode(node);
    this.coordinatorNode = new Node(Integer.MAX_VALUE - node.id(), node.host(), node.port());
    this.coordinator = new DummyCoordinator(consumerClient, metrics, mockTime);
}

Example 22 with Metadata
