hadoop windows org.codehaus.mojo：exec-maven-plugin

Question

我想在我的windows機器上安裝hadoop。 我下面這個指南：https://wiki.apache.org/hadoop/Hadoop2OnWindows 但是當我必須執行這一行：

mvn package -Pdist,native-win -DskipTests -Dtar 

我有這樣的錯誤：

[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2:exec (com 
 
pile-ms-winutils) on project hadoop-common: Command execution failed. Process ex

我已經閱讀這篇文章 build hadoop 2.2 on windows 但我無法理解如何解決。

非常感謝您的幫助。

Answer 1

您從Windows SDK命令提示符運行該命令，對吧？看看this guide I wrote recently並確保安裝了正確的工具。

Answer 2

如果您使用的是最新版本的Hadoop，即Hadoop-2.8或2.7，那麼不需要使用Maven構建Hadoop-src，而是在Windows中配置（更高版本）Hadoop的簡單方法。

Download &在c:/java/

make sure the path is this way, if java is installed in program files, then hadoop-env.cmd will not recognize java path

Download Hadoop的二進制分發安裝Java。

I am using binary distribution Hadoop-2.8.1

設置環境變量：

JAVA_HOME = "c:/Java" 
HADOOP_HOME="<your hadoop home>" 
Path= "JAVA_HOME/bin" 
Path = "HADOOP_HOME/bin" 

Hadoop will work on windows if Hadoop-src is built using maven in your windows machine. Building the Hadoop-src (distribution) will create a Hadoop binary distribution, which will work as windows native version.

但是，如果你不想這樣做，那麼下載預先builted winutils of Hadoop distribution. 這裏是一個GitHub link，其中有一些版本的winutils的Hadoop。

if the version you are using is not in the list, the follow the conventional method for setting up Hadoop on windows - link

如果你找到你的版本，然後複製粘貼文件夾的所有內容轉換成路徑：/ bin中/

Set all the .xml configuration files - Link & set JAVA_HOME path in hadoop-env.cmd file

從CMD去：

<HADOOP_HOME>/bin/> hdfs namenode -format 
<HADOOP_HOME>/sbin> start-all.cmd 

希望這有助於。
