Download the Java 1.8 64 bit version from https://java.com/en/download/ --------- If not 64 bit java there will be error when start resource node manager
Java 安装自选目录：比如 C:\java64 -----这里重要
Once installed confirm that you’re running the correct version from command line using ‘java -version’ command, output of which you can confirm in command line like this:
C:\Users>java -version
java version "1.8.0_251"
Java(TM) SE Runtime Environment (build 1.8.0_251-b08)
Java HotSpot(TM) 64-Bit Server VM (build 25.251-b08, mixed mode)
Downloaded and installed WinRAR 64 bit release from http://www.rarlab.com/download.htm that will later allow me to decompress Linux type tar.gz packages on Windows. Or use 7-zip https://www.7-zip.org/download.html
The next step was to install a Hadoop distribution. Download a binary form:
https://archive.apache.org/dist/hadoop/common/hadoop-2.9.1/hadoop-2.9.1.tar.gz
Unzip it and rename folder name to hadoop and put it under C:\Learning ------- 如果用你自己的目录，名字中间不要有空格(因为Hadoop初始开发基于linux， linux 文件名字不能有空格)。 后续设置配置文件内容时目录都要修改
It‘s time to start the Hadoop cluster with a single node.
list as below:
Add following dir to path:
c:/Learning/hadoop/data
c:/Learning/hadoop/data/namenode
c:/Learning/hadoop/data/datanode
a) C:\Learning\hadoop\etc\hadoop\core-site.xml
b) C:\Learning\hadoop\etc\hadoop\mapred-site.xml
c) C:\Learning\hadoop\etc\hadoop\hdfs-site.xml
1. install Visual C++ 2010 Redistributable Package (x64)： https://www.microsoft.com/en-us/download/details.aspx?id=14632

C:\Learning\hadoop\sbin\start-all.cmd ---- 要用管理员身份运行
四个service窗口会打开运行 ------ 任何一个都不能有错误
恭喜你可以开始运行你的Hadoop程序了！
Once all above steps were completed,opened browser and navigated to: http://localhost:8088/cluster
这里可以查看job的运行情况 log 信息。
