[Hadoop] Windows 下的 Hadoop 2.7.5 环境搭建

原文地址：

准备说明：

jdk：jdk-8u161-windows-x64.exe

hadoop：hadoop-2.7.5.tar.gz

OS：Window 10

一、JDK 安装配置

详见：

二、Hadoop 安装配置

1、在   处下载 hadoop-2.7.5.tar.gz ；

2、将 hadoop-2.7.5.tar.gz 文件解压缩（以放在 D 盘根目录下为例）；

3、配置 HADOOP_HOME 环境路径；

并追加目录下的 bin 和 sbin 文件夹路径到 PATH 变量中；

4、在命令行窗口中输入 hadoop 命令进行验证；

如果提示 JAVA_HOME 路径不对，需要去修改 %HADOOP_HOME%\etc\hadoop\hadoop-env.cmd 里的配置：

set JAVA_HOME=%JAVA_HOME%
@rem 修改为
set JAVA_HOME=C:\Progra~1\Java\jdk1.8.0_161

三、Hadoop 配置文件

core-site.xml

<configuration>
    <!-- 指定使用 hadoop 时产生文件的存放目录 -->
    <property>
        <name>hadoop.tmp.dir</name>
        <value>/D:/hadoop/workplace/tmp</value>
        <description>namenode 上本地的 hadoop 临时文件夹</description>
    </property>
	<property>
        <name>hadoop.name.dir</name>
        <value>/D:/hadoop/workplace/name</value>
    </property>
    <!-- 指定 namenode 地址 -->
    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://localhost:9000</value>
        <description>HDFS 的 URI，文件系统://namenode标识:端口号</description>
    </property>
    <property>
        <name>io.file.buffer.size</name>
        <value>131072</value>
    </property>
</configuration>

hdfs-site.xml

<configuration>
    <!-- 指定 hdfs 保存数据的副本数量 -->
    <property>
        <name>dfs.replication</name>
        <value>1</value>
        <description>副本个数，配置默认是 3，应小于 datanode 服务器数量</description>
    </property>
    <property>
        <name>dfs.namenode.name.dir</name>
        <value>/D:/hadoop/workplace/name</value>
        <description>namenode 上存储 HDFS 命名空间元数据</description>
    </property>
    <property>
        <name>dfs.datanode.data.dir</name>
        <value>/D:/hadoop/workplace/data</value>
        <description>datanode 上数据块的物理存储位置</description>
    </property>
    <property>
        <name>dfs.webhdfs.enabled</name>
        <value>true</value>
    </property>
    <property>
        <name>dfs.permissions</name>
        <value>true</value>
        <description>
            If "true", enable permission checking in HDFS.
            If "false", permission checking is turned off,
            but all other behavior is unchanged.
            Switching from one parameter value to the other does not change the mode,
            owner or group of files or directories.
    </description>
    </property>
</configuration>

mapred-site.xml

<configuration>
    <!-- MR 运行在 YARN 上 -->
    <property>
        <name>mapreduce.framework.name</name>
        <value>yarn</value>
    </property>
    <property>
        <name>mapreduce.jobhistory.address</name>
        <value>localhost:10020</value>
    </property>
    <property>
        <name>mapreduce.jobhistory.webapp.address</name>
        <value>localhost:19888</value>
    </property>
</configuration>

yarn-site.xml

<configuration>
    <!-- nodemanager 获取数据的方式是 shuffle -->
    <property>
        <name>yarn.nodemanager.aux-services</name>
        <value>mapreduce_shuffle</value>
    </property>
	<property>
       <name>yarn.nodemanager.aux-services.mapreduce.shuffle.class</name>
       <value>org.apache.hadoop.mapred.ShuffleHandler</value>
    </property>
</configuration>

四、格式化 namenode

hadoop namenode –format 出现异常：

DEPRECATED: Use of this script to execute hdfs command is deprecated.
Instead use the hdfs command for it.
18/02/09 12:18:11 ERROR util.Shell: Failed to locate the winutils binary in the hadoop binary path
java.io.IOException: Could not locate executable D:\hadoop\bin\winutils.exe in the Hadoop binaries.
        at org.apache.hadoop.util.Shell.getQualifiedBinPath(Shell.java:382)
        at org.apache.hadoop.util.Shell.getWinUtilsPath(Shell.java:397)
        at org.apache.hadoop.util.Shell.<clinit>(Shell.java:390)

        at org.apache.hadoop.hdfs.server.namenode.NameNode.<clinit>(NameNode.java:265)

下载 压缩包，解压并替换掉 hadoop\bin 目录下的文件，然后再重新格式化：

C:\Users\Memento>hadoop namenode -format
DEPRECATED: Use of this script to execute hdfs command is deprecated.
Instead use the hdfs command for it.

五、启动 Hadoop

C:\Users\Memento>start-all.cmd
This script is Deprecated. Instead use start-dfs.cmd and start-yarn.cmd
starting yarn daemons

如果出现如下异常，提示说无法解析 master 地址：

org.apache.hadoop.yarn.exceptions.YarnRuntimeException: java.io.IOException: Failed on local exception: java.net.SocketException: Unresolved address; Host Details : local host is: "master"; destination host is: (unknown):0

此时需要在 C:\Windows\System32\drivers\etc\hosts 文件中追加 master 的映射：192.168.1.104    master

然后再重新执行启动命令 start-all.cmd；

随后会出现四个命令窗口，依次如下：

1、Apache Hadoop Distribution - hadoop namenode

2、Apache Hadoop Distribution - yarn resourcemanager

3、Apache Hadoop Distribution - yarn nodemanager

4、Apache Hadoop Distribution - hadoop datanode

六、JPS 查看启动进程

C:\Users\XXXXX>jps
13460 Jps
14676 NodeManager
12444 NameNode
14204 DataNode
14348 ResourceManager

七、MapReduce 任务和 hdfs 文件

通过浏览器浏览 localhost:8080 和 localhost:50070 访问浏览：

至此，Hadoop 在 Windows 下的环境搭建完成！

关闭 hadoop

C:\Users\XXXXX>stop-all.cmd
This script is Deprecated. Instead use stop-dfs.cmd and stop-yarn.cmd
成功: 给进程发送了终止信号，进程的 PID 为 27204。
成功: 给进程发送了终止信号，进程的 PID 为 7884。
stopping yarn daemons
成功: 给进程发送了终止信号，进程的 PID 为 20464。
成功: 给进程发送了终止信号，进程的 PID 为 12516。

信息: 没有运行的带有指定标准的任务。
