hadoop window 配置总结

## 核心问题 ##

### 1.是windows环境中没有配置hadoophome.配置之后加入winutils工具 ###

[https://github.com/steveloughran/winutils  推荐使用 ][https_github.com_steveloughran_winutils_ _]2.7.1  不要使用2.2.0 （有很多问题）

a.增加用户变量HADOOP\_HOME，值是下载的zip包解压的目录，

b.系统变量path里增加%HADOOP\_HOME%\\bin ，

c.CLASSPATH下配置%HADOOP\_HOME%\\bin\\winutils.exe

**注意配置好一定要重启**

### 2.pom中执行的hadoop的版本与window环境中的hadoop的版本不一致 ###

<dependency>
        <groupId>org.apache.hadoop</groupId>
        <artifactId>hadoop-common</artifactId>
        <version>2.7.1</version>
    </dependency>

和上面的版本配合使用

### 以下是具体的 报错方法及其细节 ###

java.io.IOException: Could not locate executable null\\bin\\winutils.exe in the Hadoop binaries

其实就是hadoop的环境变量有问题  可以看一下源码就是路径找不到为空

## 注意配置好一定要重启 ##

这里要理解的是，**一个程序启动时，环境变量被复制到该程序所在的环境中，在该程序执行过程中不会被除该程序以外的其他程序所改变。**也就是说，假设我们启动了一个cmd程序，然后通过控制面板修改了环境变量设置，但是已经启动了的cmd所拥有的环境变量并不会被改变。如果我们在修改环境变量之后启动cmd程序，则该程序将拥有新的环境变量。

那么结论就很明显了：修改环境变量之后，如果受影响的是应用程序，那么只要简单地重新启动此应用程序，环境变量的修改就会反映到该程序中，而不必重新启动计算机；但是，如果受影响的是系统服务，就必须重新启动才能将环境变量的修改反映到系统服务中（因为没有办法在不重启计算机的情况下重新启动系统服务管理器）。

You are missing winutils.exe, a hadoop binary. Depending upon x64 bit / x32 bit system, download the winutils.exe file & set your hadoop home pointing to it.

1st way :

1.Download the file

2.Create hadoop folder in Your System ex " C:"

3.Create bin folder in hadoop directory ex : C:\\hadoop\\bin

4.paste winutils.exe in bin ex: C:\\hadoop\\bin\\winuitls.exe

5.In User Variables in System Properties -> Advance System Settings

Create New Variable Name: HADOOP\_HOME Path: C:\\hadoop\\

2nd Way :

You can set hadoop home directly in Your Java Program with the following Command like this :

System.setProperty("hadoop.home.dir","C:\hadoop" );

# #

解决办法：

下载winutils地址[https://github.com/steveloughran/winutils ][https_github.com_steveloughran_winutils_ _]下载解压

配置环境变量  
增加用户变量HADOOP\_HOME，值是下载的zip包解压的目录，然后在系统变量path里增加%HADOOP\_HOME%\\bin 即可。
