问题描述
- 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?)
- 是2.5.2中移除的jobtracker >
- 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。
- 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?)
- is the jobtracker removed in 2.5.2
- 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.
