标签:本地 ctf 文件 任务计划 现在 ffffff 管理 郑州 http 一、Hadoop集群安装 1. 环境准备 (1) 准备三台机器:hadoop0(192.168.11.10)、hadoop1(192.168.11.11)、hadoop2(192.168.11.12) (2)每台机器安装好JAVA环境以及SSH打通(SSH免密登录;关闭防火墙) 2. 下载Hadoop安装包 并解压至相关目录 3. 配置Hadoop相关配置文件 (1)hadoop-env.sh 添加Java环境变量 (2)core-site.xml (3)hdfs-site.xml (4)mapred-site.xml (5)yarn-site.xml (6)slaves 配置完成以上几个配置文件之后,将其拷贝至另外两台机器。 4.启动Hadoop集群 (1)执行命令格式化name node:./bin/hadoop namenode -format (2)启动Hadoop:./sbin/start-all.sh (3)jps查看每个机器进程情况 - 主节点 NameNode -从节点 DataNode 5. 问题 (1)tmp/nm-local-dir is not a valid path. Path should be with file scheme or without schem 解决:使用hadoop默认的tmp目录 Win7: win7出现卡顿如何解决 标签:本地 ctf 文件 任务计划 现在 ffffff 管理 郑州 http 原文地址:https://www.cnblogs.com/penguin0601/p/13470313.htmlexport JAVA_HOME=/home/vagrant/share/jdk1.8.0_211
