YARN 作业历史记录不可访问

我正在使用来自源代码的最新 hadoop 版本 3.0.0。我已经启动并运行了时间轴服务，并配置了 hadoop 以将其用于作业历史记录。但是，当我单击资源管理器 UI 中的历史记录时，出现以下错误：-

HTTP ERROR 404

Problem accessing /jobhistory/job/job_1444395439959_0001. Reason:

    NOT_FOUND

有人可以指出我在这里缺少什么吗？以下是我的yarn-site.xml：-

<configuration>

<!-- Site specific YARN configuration properties -->

如果您想通过 YARN RM Web UI 查看日志，则需要启用日志聚合。为此，您需要在yarn-site.xml中设置以下参数：

  <property>
      <name>yarn.log-aggregation-enable</name>
      <value>true</value>
  </property>
  <property>
     <name>yarn.nodemanager.remote-app-log-dir</name>
     <value>/app-logs</value>
  </property>
  <property>
      <name>yarn.nodemanager.remote-app-log-dir-suffix</name>
      <value>logs</value>
  </property>

如果不启用日志聚合，则网管会将日志存储在本地。通过上述设置，日志将聚合在 HDFS 中的“/app-logs/{username}/logs/”处。在此文件夹下，您可以找到迄今为止运行的所有应用程序的日志。同样，日志保留由配置参数“yarn.log-aggregation.retain-seconds”（保留聚合日志的时间）决定。

当 MapReduce 应用程序运行时，您可以从 YARN 的 Web UI 访问日志。应用程序完成后，日志将通过 Job History Server 提供。

另外，在yarn-site.xml中设置以下配置参数：

<property>
  <name>yarn.log.server.url</name>
  <value>http://{job-history-hostname}:8188/jobhistory/logs</value>
</property>
