Hadoop 2.2.0 jobtracker没有启动 [英] Hadoop 2.2.0 jobtracker is not starting

问题描述

看来我没有使用Hadoop 2.2.0的 jobtracker 。 JPS没有显示它，没有人在端口50030上侦听，并且在 logs jobtracker 的日志c>文件夹。这是因为YARN吗？如何配置和启动作业跟踪器？

解决方案

如果您使用的是YARN框架，则不存在 jobtracker 在里面。它的功能被拆分并由 ResourceManager 和 ApplicationMaste r取代。这里预计 jps 运行YARN时的印刷品

  $ jps 
 18509 Jps 
 17107 NameNode 
 17170 DataNode 
 17252 ResourceManager 
 17309 NodeManager 
 17626 JobHistoryServer 
  

It seems I have no jobtracker with Hadoop 2.2.0. JPS does not show it, there is no one listening on port 50030, and there are no logs about the jobtracker inside the logs folder. Is this because of YARN? How can I configure and start the job tracker?

解决方案

If you are using YARN framework, there is no jobtracker in it. Its functionality is split and replaced by ResourceManager and ApplicationMaster. Here is expected jps prinout while running YARN

$jps
18509 Jps
17107 NameNode
17170 DataNode
17252 ResourceManager
17309 NodeManager
17626 JobHistoryServer
