问题描述


  1. 在每个应用程序的mapreduce webconsole中都有一个跟踪ui链接,它指向xx:19888 / jobhistory /,但是如何在19888上启动服务(我已经启动了4个服务:资源管理器,yarn-node-manager,hdfs-name-node,hdfs-data-node,我错过了什么?)

  2. 是2.5.2中移除的jobtracker
  3. >
  4. 我想检查为我的工作生成的job.xml,我在哪里可以找到它。我指定了mapreduce.jobtracker.jobhistory.location,但没有任何内容。

谢谢。



尝试// jhs_host

:port /默认HTTP端口是19888.



确保您的hadoop服务正在运行。


  1. in the mapreduce webconsole for each application there is a tracking ui link which points to xx:19888/jobhistory/, but how to start the service on 19888 (i have started 4 services: yarn-resource-manager, yarn-node-manager, hdfs-name-node, hdfs-data-node, what i have missed?)
  2. is the jobtracker removed in 2.5.2
  3. I want to check the job.xml generated for my job, where can i find it. I have specified "mapreduce.jobtracker.jobhistory.location" but nothing is there

Thank you.

解决方案

Please try 'jps' command to verify all the services are running.

try //jhs_host:port/ Default HTTP port is 19888."

Make sure that your hadoop services are running.
