windows下安装并启动hadoop2.7.2

　　64位windows安装hadoop没必要倒腾Cygwin，直接解压官网下载hadoop安装包到本地->最小化配置4个基本文件->执行1条启动命令->完事。一个前提是你的电脑上已经安装了jdk，设置了java环境变量。下面把这几步细化贴出来，以hadoop2.7.2为例

　　1、下载hadoop安装包就不细说了：http://hadoop.apache.org/->左边点Releases->点mirror site->点http://mirrors.tuna.tsinghua.edu.cn/apache/hadoop/common->下载hadoop-2.7.2.tar.gz；

　　2、解压也不细说了：复制到D盘根目录直接解压，出来一个目录D:\hadoop-2.7.2，配置到环境变量HADOOP_HOME中，在PATH里加上%HADOOP_HOME%\bin；点击http://download.csdn.net/detail/wuxun1997/9841472下载相关工具类，直接解压后把文件丢到D:\hadoop-2.7.2\bin目录中去，将其中的hadoop.dll在c:/windows/System32下也丢一份；

　　3、去D:\hadoop-2.7.2\etc\hadoop找到下面4个文件并按如下最小配置粘贴上去：

core-site.xml

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

hdfs-site.xml

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

mapred-site.xml

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

yarn-site.xml

<configuration>    <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>

　　4、启动windows命令行窗口，进入hadoop-2.7.2\bin目录，执行下面2条命令，先格式化namenode再启动hadoop

D:\hadoop-2.7.2\bin>hadoop namenode -formatDEPRECATED: Use of this script to execute hdfs command is deprecated.Instead use the hdfs command for it.17/05/13 07:16:40 INFO namenode.NameNode:

　　通过jps命令可以看到4个进程都拉起来了，到这里hadoop的安装启动已经完事了。接着我们可以用浏览器到localhost:8088看mapreduce任务，到localhost:50070->Utilites->Browse the file system看hdfs文件。如果重启hadoop无需再格式化namenode，只要stop-all.cmd再start-all.cmd就可以了。
