方法名:getInitialEndpoints

ZKClusterCoordinatorDriver.getInitialEndpoints介绍

[英]Returns the set of Drillbits registered at the time of the #build()call. Should be empty for a cluster managed by YARN.
[中]返回在#build()调用时注册的钻取数据集。对于由纱线管理的群集,应为空。

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);
}

/**
 * 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
