原作者: [db:作者] 来自: [db:来源] 收藏 邀请

本文整理汇总了Java中org.apache.hadoop.mapreduce.jobhistory.Event的典型用法代码示例。如果您正苦于以下问题:Java Event类的具体用法?Java Event怎么用?Java Event使用的例子?那么恭喜您, 这里精选的类代码示例或许可以为您提供帮助。



Event类属于org.apache.hadoop.mapreduce.jobhistory包,在下文中一共展示了Event类的6个代码示例,这些例子默认根据受欢迎程度排序。您可以为喜欢或者感觉有用的代码点赞,您的评价将有助于我们的系统推荐出更棒的Java代码示例。

示例1: testRecoverySuccessAttempt

import org.apache.hadoop.mapreduce.jobhistory.Event; //导入依赖的package包/类
@Test
public void testRecoverySuccessAttempt() {
  LOG.info("--- START: testRecoverySuccessAttempt ---");

  long clusterTimestamp = System.currentTimeMillis();
  EventHandler mockEventHandler = mock(EventHandler.class);
  MapTaskImpl recoverMapTask = getMockMapTask(clusterTimestamp,
      mockEventHandler);

  TaskId taskId = recoverMapTask.getID();
  JobID jobID = new JobID(Long.toString(clusterTimestamp), 1);
  TaskID taskID = new TaskID(jobID,
      org.apache.hadoop.mapreduce.TaskType.MAP, taskId.getId());

  //Mock up the TaskAttempts
  Map<TaskAttemptID, TaskAttemptInfo> mockTaskAttempts =
      new HashMap<TaskAttemptID, TaskAttemptInfo>();

  TaskAttemptID taId1 = new TaskAttemptID(taskID, 2);
