Examples with NodeState org.apache.camel.component.zookeepermaster.group.NodeState used on opensource projects

Example 1 with NodeState

use of org.apache.camel.component.zookeepermaster.group.NodeState in project camel by apache.

the class ZooKeeperMultiGroup method isMaster.

@Override
public boolean isMaster(String name) {
    List<ChildData<T>> children = getActiveChildren();
    Collections.sort(children, getSequenceComparator());
    for (ChildData child : children) {
        NodeState node = (NodeState) child.getNode();
        if (node.id.equals(name)) {
            return child.getPath().equals(getId());
        }
    }
    return false;
}

Example 2 with NodeState

use of org.apache.camel.component.zookeepermaster.group.NodeState in project camel by apache.

the class ZooKeeperGroupTest method testMaster.

@Test
public void testMaster() throws Exception {
    putChildData(group, PATH + "/001", "container1");
    putChildData(group, PATH + "/002", "container2");
    putChildData(group, PATH + "/003", "container3");
    NodeState master = group.master();
    assertThat(master, notNullValue());
    assertThat(master.getContainer(), equalTo("container1"));
}

private static void putChildData(ZooKeeperGroup<NodeState> group, String path, String container) throws Exception {
    NodeState node = new NodeState("test", container);
    ByteArrayOutputStream data = new ByteArrayOutputStream();
    new ObjectMapper().disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES).writeValue(data, node);
