本文整理了Java中org.apache.drill.yarn.zk.ZKClusterCoordinatorDriver.build()方法的一些代码示例，展示了ZKClusterCoordinatorDriver.build()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ZKClusterCoordinatorDriver.build()方法的具体详情如下：
包路径：org.apache.drill.yarn.zk.ZKClusterCoordinatorDriver
类名称：ZKClusterCoordinatorDriver
方法名：build

ZKClusterCoordinatorDriver.build介绍

[英]Builds and starts the ZooKeeper cluster coordinator, translating any errors that occur. After this call, the listener will start receiving messages.
[中]构建并启动ZooKeeper群集协调器，转换发生的任何错误。在这个呼叫之后，侦听器将开始接收消息。

代码示例

代码示例来源：origin: apache/drill

/**
 * Called during AM startup to initialize ZK. Checks if any Drillbits are
 * already running. These are "unmanaged" because the AM could not have
 * started them (since they predate the AM.)
 */
public void start(RegistryHandler controller) {
 this.registryHandler = controller;
 try {
  zkDriver.build();
 } catch (ZKRuntimeException e) {
  LOG.error("Failed to start ZK monitoring", e);
  throw new AMWrapperException("Failed to start ZK monitoring", e);
 }
 for (DrillbitEndpoint dbe : zkDriver.getInitialEndpoints()) {
  String key = toKey(dbe);
  registry.put(key, new DrillbitTracker(key, dbe));
  // Blacklist the host for each unmanaged drillbit.
  controller.reserveHost(dbe.getAddress());
  LOG.warn("Host " + dbe.getAddress()
    + " already running a Drillbit outside of YARN.");
 }
 zkDriver.addDrillbitListener(this);
}

代码示例来源：origin: apache/drill

/**
 * Basic setup: start a ZK and verify that the initial endpoint list is empty.
 * Also validates the basics of the test setup (mock server, etc.)
 *
 * @throws Exception
 */
@Test
public void testBasics() throws Exception {
 try (TestingServer server = new TestingServer()) {
  server.start();
  String connStr = server.getConnectString();
  ZKClusterCoordinatorDriver driver = new ZKClusterCoordinatorDriver()
    .setConnect(connStr, "drill", "drillbits").build();
  assertTrue(driver.getInitialEndpoints().isEmpty());
  driver.close();
  server.stop();
 }
}

代码示例来源：origin: apache/drill

String connStr = server.getConnectString();
ZKClusterCoordinatorDriver driver = new ZKClusterCoordinatorDriver()
  .setConnect(connStr, TEST_ZK_ROOT, TEST_CLUSTER_ID).build();
   .setConnect(connStr, TEST_ZK_ROOT, TEST_CLUSTER_ID).build();
   .setConnect(connStr, TEST_ZK_ROOT, PROBE_CLUSTER_ID).build();
   .setConnect(connStr, PROBE_ZK_ROOT, TEST_CLUSTER_ID).build();
   .setConnect(connStr, TEST_ZK_ROOT, TEST_CLUSTER_ID).build();

代码示例来源：origin: apache/drill

.setConnect(connStr, ZK_ROOT, CLUSTER_ID).build();
List<DrillbitEndpoint> bits = driver.getInitialEndpoints();
assertEquals(1, bits.size());

代码示例来源：origin: apache/drill

.setPorts(TEST_USER_PORT, TEST_CONTROL_PORT, TEST_DATA_PORT).build();
ZKRegistry registry = new ZKRegistry(driver);
TestRegistryHandler handler = new TestRegistryHandler();
