准備說明：
jdk：jdk-8u161-windows-x64.exe
hadoop：hadoop-2.7.5.tar.gz
OS：Window 10
一、JDK 安裝配置
詳見：JDK 環境配置（圖文）
二、Hadoop 安裝配置
1、在 http://hadoop.apache.org/releases.html 處下載 hadoop-2.7.5.tar.gz ；
2、將 hadoop-2.7.5.tar.gz 文件解壓縮（以放在 D 盤根目錄下為例）；
3、配置 HADOOP_HOME 環境路徑；
並追加目錄下的 bin 和 sbin 文件夾路徑到 PATH 變量中；
4、在命令行窗口中輸入 hadoop 命令進行驗證；
如果提示 JAVA_HOME 路徑不對，需要去修改 %HADOOP_HOME%\etc\hadoop\hadoop-env.cmd 里的配置：
set JAVA_HOME=%JAVA_HOME% @rem 修改為 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 時產生文件的存放目錄 -->
<property>
<name>hadoop.tmp.dir</name>
<value>/D:/hadoop/workplace/tmp</value>
<description>namenode 上本地的 hadoop 臨時文件夾</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，文件系統://namenode標識:端口號</description>
</property>
<property>
<name>io.file.buffer.size</name>
<value>131072</value>
</property>
</configuration>
hdfs-site.xml
<configuration>
<!-- 指定 hdfs 保存數據的副本數量 -->
<property>
<name>dfs.replication</name>
<value>1</value>
<description>副本個數，配置默認是 3，應小於 datanode 服務器數量</description>
</property>
<property>
<name>dfs.namenode.name.dir</name>
<value>/D:/hadoop/workplace/name</value>
<description>namenode 上存儲 HDFS 命名空間元數據</description>
</property>
<property>
<name>dfs.datanode.data.dir</name>
<value>/D:/hadoop/workplace/data</value>
<description>datanode 上數據塊的物理存儲位置</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 運行在 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 獲取數據的方式是 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 出現異常：
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.hdfs.server.namenode.NameNode.<clinit>(NameNode.java:265)
下載 window-hadoop-bin.zip 壓縮包，解壓並替換掉 hadoop\bin 目錄下的文件，然后再重新格式化：

五、啟動 Hadoop
C:\Users\Memento>start-all.cmd This script is Deprecated. Instead use start-dfs.cmd and start-yarn.cmd starting yarn daemons
如果出現如下異常，提示說無法解析 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
此時需要在 C:\Windows\System32\drivers\etc\hosts 文件中追加 master 的映射：192.168.1.104 master
然后再重新執行啟動命令 start-all.cmd；
隨后會出現四個命令窗口，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 查看啟動進程
C:\Users\XXXXX>jps 13460 Jps 14676 NodeManager 12444 NameNode 14204 DataNode 14348 ResourceManager
七、MapReduce 任務和 hdfs 文件
通過瀏覽器瀏覽 localhost:8080 和 localhost:50070 訪問瀏覽：
至此，Hadoop 在 Windows 下的環境搭建完成！
關閉 hadoop
C:\Users\XXXXX>stop-all.cmd This script is Deprecated. Instead use stop-dfs.cmd and stop-yarn.cmd 成功: 給進程發送了終止信號，進程的 PID 為 27204。 成功: 給進程發送了終止信號，進程的 PID 為 7884。 stopping yarn daemons 成功: 給進程發送了終止信號，進程的 PID 為 20464。 成功: 給進程發送了終止信號，進程的 PID 為 12516。 信息: 沒有運行的帶有指定標准的任務。
