打包好的已配置好的hadoop  我這裡用的是2.6.5 其中包括重要的幾個dll檔案是hadoop不自帶的。

配置到環境變：

環境變量HADOOP_HOME中是安裝的路徑，在PATH里加上%HADOOP_HOME%\bin；下載相關工具類，直接解壓後把檔案丟到E:\hadoop-2.6.5\bin目錄中去，將其中的hadoop.dll在c:/windows/System32下也丟一份；

用記事本開啟 hadoop2.6.5\etc\hadoop\hadoop-env.cmd檔案，修改JAVA_HOME為你自己jdk路徑。

windows下安裝並啟動hadoop2.6.5

　　2、解壓也不細說了：複製到E盤根目錄直接解壓，出來一個目錄E:\hadoop-2.6.5

       3、去E:\hadoop-2.6.5\etc\hadoop找到下面4個檔案並按如下最小配置貼上上去：

core-site.xml

1. <configuration>
2.     <property>
3.         <name>fs.defaultFS</name>
4.         <value>hdfs://localhost:9000</value>
5.     </property>
6. </configuration>

1. <configuration>
2.     <property>
3.         <name>dfs.replication</name>
4.         <value>1</value>
5.     </property>
6.     <property>
7.         <name>dfs.namenode.name.dir</name>
8.         <value>file:/hadoop/data/dfs/namenode</value>
9.     </property>
10.     <property>
11.         <name>dfs.datanode.data.dir</name>
12.         <value>file:/hadoop/data/dfs/datanode</value>
13.     </property>
14. </configuration>

mapred-site.xml

1. <configuration>
2.     <property>
3.         <name>mapreduce.framework.name</name>
4.         <value>yarn</value>
5.     </property>
6. </configuration>

1. <configuration>
2.     <property>
3.         <name>yarn.nodemanager.aux-services</name>
4.         <value>mapreduce_shuffle</value>
5.     </property>
6.     <property>
7.         <name>yarn.nodemanager.aux-services.mapreduce.shuffle.class</name>
8.         <value>org.apache.hadoop.mapred.ShuffleHandler</value>
9.     </property>
10. </configuration>

4、啟動windows命令列視窗，進入hadoop-2.6.5\bin目錄，執行下面2條命令，先格式化namenode再啟動hadoop



E:\hadoop-2.6.5\bin>hadoop namenode -format




E:\hadoop-2.6.5\bin>cd ..\sbin


E:\hadoop-2.6.5\sbin>start-all.cmd
This script is Deprecated. Instead use start-dfs.cmd and start-yarn.cmd
starting yarn daemons


E:\hadoop-2.6.5\sbin>jps
4944 DataNode
5860 NodeManager
3532 Jps
7852 NameNode
7932 ResourceManager
