Hadoop 搭建单节点集群（伪集群）

目的

本文档介绍如何设置和配置单节点 Hadoop 安装，以便您可以使用 Hadoop MapReduce 和 Hadoop 分布式文件系统 (HDFS) 快速执行简单的操作。

学习接触Hadoop，但是生产环境不建议使用。

环境配置

环境	版本
系统	centos7.6
JDK	java11
Hadoop	3.3.3

先决条件

支持的平台

支持 GNU/Linux 作为开发和生产平台。Hadoop 已在具有 2000 个节点的 GNU/Linux 集群上进行了演示。
Windows 也是受支持的平台，但以下步骤仅适用于 Linux。要在 Windows 上设置 Hadoop，请参阅wiki 页面。

所需基础软件

必须安装 Java™。这里使用了java11，具体安装方式可以参考： linux安装java11
如果要使用可选的启动和停止脚本，则必须安装 ssh 并且必须运行 sshd 才能使用管理远程 Hadoop 守护程序的 Hadoop 脚本。此外，建议同时安装 pdsh 以更好地管理 ssh 资源。

下载安装包

要获得 Hadoop 发行版，请从Apache 下载镜像之一下载最近的稳定版本。

以hadoop3.3.3为例：

wget https://dlcdn.apache.org/hadoop/common/hadoop-3.3.3/hadoop-3.3.3.tar.gz --no-check-certificate

--no-check-certificate 声明不检查证书

解压安装包

tar -xvf hadoop-3.3.3.tar.gz

配置Hadoop单点集群

配置JDK Hadoop环境变量

编辑在解压包下的 etc/hadoop/hadoop-env.sh 编辑

export JAVA_HOME=/home/install/jdk/jdk-11

Hadoop命令说明

 $ bin/hadoop

配置 core-site.xml

编辑解压包下的 etc/hadoop/core-site.xml 文件，添加如下配置

<configuration>
    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://localhost:9000</value>
    </property>
</configuration>

配置 hdfs-site.xml

编辑解压包下的 etc/hadoop/hdfs-site.xml 文件，添加如下配置

<configuration>
    <property>
        <name>dfs.replication</name>
        <value>1</value>
    </property>
</configuration>

设置无密码SSH

创建ssh公私钥

 ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa

以公钥创建授权key

cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

授权

 chmod 0600 ~/.ssh/authorized_keys

开始安装

格式化namenode

 bin/hdfs namenode -format

正确的格式化命令执行结果见下方 执行nameNode格式化命令成功控制台输出

启动 NameNode 守护进程和 DataNode 守护进程

sbin/start-dfs.sh

启动成功访问势力

NameNode访问地址： http://localhost:9870/

访问效果如下：

执行nameNode格式化命令成功控制台输出：
