5.3执行: 下面介绍在本地运行一个MapReduce,如果你想在YARN上执行任务,参考YARN on a Single Node: 1文件系统格式: bin/hdfs namenode -format 2.开启 NameNode进程和 DataNode进程 sbin/start-dfs.sh hadoop后台日志写入到 $HADOOP_LOG_DIR (默认是 $HADOOP_HOME/logs) 3.为NameNode配置web界面;默认下这个...
这个文档描述了如何安装配置hadoop集群,从几个节点到上千节点。为了学习hadoop,你可能先从单节点入手 (查看 Single Node Setup).这里有中文版hadoop2.7【单节点】单机、伪分布、分布式安装指导 http://www.aboutyun.com/thread-12798-1-1.html 这个文档不包括:hadoop在安全模式下配置和HA【高可用配置】,后面在更新...

Hadoop requires SSH access to manage its nodes, i.e. remote machines plus your local machine if you want to use Hadoop on it (which is what we want to do in this short tutorial). For our single-node setup of Hadoop, we therefore need to configure SSH access tolocalhostfor thehduserus...
