一、安装Java

1. 下载Java

进入下载页面Java Archive Downloads - Java SE 8

Java SE Development Kit 8u191中

选择适合操作系统的下载文件

在安装好的路径下，将Java目录复制到C:\根目录下，形成C:\Java\jdk1.8.0_191目录结构

2. 设置环境变量

注意：要保证jdk所在的路径中不能包含空格，比如Program Files中间是有空格的，建议参照下图中的路径

二、安装Hadoop

1. 下载hadoop-3.3.0

进入下载页面

https://archive.apache.org/dist/hadoop/common/hadoop-3.3.0/

选择hadoop-3.3.0.tar.gz下载

https://archive.apache.org/dist/hadoop/common/hadoop-3.3.0/hadoop-3.3.0.tar.gz

解压到C:\hadoop-3.3.0目录，形成C:\hadoop-3.3.0\bin这种目录层次

2. 下载winutils替换hadoop-3.3.0\bin目录

下载winutils

https://github.com/s911415/apache-hadoop-3.1.0-winutils

将其中bin目录替换到C:\hadoop-3.3.0\下的bin目录

3. 设置环境变量

4. 修改配置

C:\hadoop-3.3.0\etc\hadoop目录下有4个配置文件

C:\hadoop-3.3.0\etc\hadoop\core-site.xml

<configuration>
  <property>
    <name>fs.default.name</name>
    <value>hdfs://localhost:9820</value>
  </property>
</configuration>

C:\hadoop-3.3.0\etc\hadoop\hdfs-site.xml

<configuration>
  <property>
    <name>dfs.replication</name>
    <value>1</value>
  </property>
  <property>
    <name>dfs.namenode.name.dir</name>
    <value>file:///C:/hadoop-3.3.0/data/dfs/namenode</value>
  </property>
  <property>
    <name>dfs.datanode.data.dir</name>
    <value>file:///C:/hadoop-3.3.0/data/dfs/datanode</value>
  </property>
</configuration>

C:\hadoop-3.3.0\etc\hadoop\mapred-site.xml

<configuration>
  <property>
    <name>mapreduce.framework.name</name>
    <value>yarn</value>
    <description>MapReduce framework name</description>
  </property>
</configuration>

C:\hadoop-3.3.0\etc\hadoop\yarn-site.xml

<configuration>

  <!-- Site specific YARN configuration properties -->
  <property>
    <name>yarn.nodemanager.aux-services</name>
    <value>mapreduce_shuffle</value>
    <description>Yarn Node Manager Aux Service</description>
  </property>

</configuration>

5. 格式化目录

创建数据目录

C:\hadoop-3.3.0\data\dfs\namenode

C:\hadoop-3.3.0\data\dfs\datanode

cd C:\hadoop-3.3.0\bin
hdfs namenode -format

注意：-format中开头的短横容易写成全角下的短横，这样会导致错误，一定要用半角短横

选择Y

6. 验证服务

C:\hadoop-3.3.0\sbin> jps
17504 NameNode
17584 Jps
20944 NodeManager
3852 DataNode
4572 ResourceManager
PS C:\hadoop-3.3.0\sbin>

7. 启动

进入C:\hadoop-3.3.0\sbin

执行start-dfs.cmd文件

cd C:\hadoop-3.3.0\sbin
start-dfs.cmd

执行start-yarn.cmd文件

cd C:\hadoop-3.3.0\sbin
start-yarn.cmd

可能问题：

如果出现报错：

Windows11安装hadoop-3.3.0,hadoop,大数据,linux

java.lang.NoClassDefFoundError: org/apache/hadoop/yarn/server/timelineservice/collector/TimelineColl

可以复制
C:\hadoop-3.3.0\share\hadoop\yarn\timelineservice\hadoop-yarn-server-timelineservice-3.3.0.jar
到
C:\hadoop-3.3.0\share\hadoop\yarn

Data node web page: http://localhost:9864/datanode.html

Yarn web page: http://localhost:8088/cluster
