示例1: init

import org.apache.hadoop.metrics2.util.Servers; //导入依赖的package包/类
public void init(SubsetConfiguration conf) {
  LOG.debug("Initializing the GangliaSink for Ganglia metrics.");

  this.conf = conf;

  // Take the hostname from the DNS class.
  if (conf.getString("slave.host.name") != null) {
    hostName = conf.getString("slave.host.name");
  } else {
    try {
      hostName = DNS.getDefaultHost(
          conf.getString("dfs.datanode.dns.interface", "default"),
          conf.getString("dfs.datanode.dns.nameserver", "default"));
    } catch (UnknownHostException uhe) {
      LOG.error(uhe);
      hostName = "UNKNOWN.example.com";
    }
  }

  // load the gannglia servers from properties
  metricsServers = Servers.parse(conf.getString(SERVERS_PROPERTY),
      DEFAULT_PORT);

  // extract the Ganglia conf per metrics
  gangliaConfMap = new HashMap<String, GangliaConf>();
  loadGangliaConf(GangliaConfType.units);

  // see if sparseMetrics is supported. Default is false
  supportSparseMetrics = conf.getBoolean(SUPPORT_SPARSE_METRICS_PROPERTY,
