示例1: JobTrackerHAServiceTarget
import org.apache.hadoop.ha.NodeFencer; //导入依赖的package包/类
public JobTrackerHAServiceTarget(Configuration conf, String jtId) {
this.logicalName = HAUtil.getLogicalName(conf);
this.jtId = jtId;
// Make a copy of the conf, and override configs based on the
// target node -- not the node we happen to be running on.
JobConf targetConf = new JobConf(conf);
HAUtil.setGenericConf(targetConf, logicalName, jtId, HAUtil.JOB_TRACKER_SPECIFIC_KEYS);
this.addr = HAUtil.getJtHaRpcAddress(targetConf, jtId);
this.autoFailoverEnabled = targetConf.getBoolean(
HAUtil.MR_HA_AUTO_FAILOVER_ENABLED_KEY,
HAUtil.MR_HA_AUTO_FAILOVER_ENABLED_DEFAULT);
