嗯，用户在使用Hadoop 3.1.3运行WordCount示例时遇到了连接ResourceManager的问题，需要查看相关日志来排查。首先，我需要回忆Hadoop的日志文件通常存放在哪里。根据引用[3]和[4]，Hadoop的配置文件在$HADOOP_HOME/...

这个错误是由于无法连接到Hadoop集群中的ResourceManager引起的，可能是由于ResourceManager宕机或网络故障导致的。您可以尝试以下几个步骤来解决此问题： 1. 检查Hadoop集群的状态，确保所有服务都已启动并正常...

Yarn资源调度器概述 思考： 1）如何管理集群资源？ 2）如何给任务合理分配资源？ Yarn是一个资源调度平台，负责为运算程序提供服务器运算资源，相当于一个分布式的操作系统平台，而MapReduce等运算程序则相当于运行于操作系统之上的应用程序。 1、Yarn基础架构 Yarn主要由ResourceManager、NodeManager、ApplicationMaster和Container等组件构成。 2、Yarn工作机制 ​ （1）MR程序提交到客户端所在的节点。 ​ （2）Ya
