如何开始并检查hadoop 2.5.2上的工作历史 [英] how to start and check job history on hadoop 2.5.2

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. 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.
