hadoop2.6在win7上的编译-报错处理

编译前准备，需要安装64位的jdk、protoc（别小看这个，非常重要，我在此耽误好多时候，具体见后面的error）

1、   下载hadoop源码（hadoop-2.6.0-src.tar.gz）并解压：

如解压到：D:\app\workspace\hadoop\hadoop-2.6.0-src

Cmd进入到dos命令方式

Cd /d D:\app\workspace\hadoop\hadoop-2.6.0-src

2、   编译：

Cd  hadoop-maven-plugins

hadoop-maven-plugins

cd ..

mvn eclipse:eclipse -DskipTests

3、   报错信息

1)        Failed to execute goalorg.apache.hadoop:hadoop-maven-plugins:2.6.0:protoc

[ERROR] Failed to execute goalorg.apache.hadoop:hadoop-maven-plugins:2.6.0:protoc (compile-protoc) on projecthadoop-co

mmon: org.apache.maven.plugin.MojoExecutionException: 'protoc--version' did not return a version -> [Help 1]

org.apache.maven.lifecycle.LifecycleExecutionException: Failed toexecute goal org.apache.hadoop:hadoop-maven-plugins:2.6.0:protoc(compile-protoc) on project hadoop-common:org.apache.maven.plugin.MojoExecutionException: 'protoc --version' did notreturn a version

解决方法：

下载protoc-2.5.0-win32.zip，解压，将protoc.exe拷贝到C:\Windows\System32下

安装protobuf-2.5.0

若仍有上述错误，需检查jdk版本（这个把我弄了好久：之前我是1.7，没注意是32位，网上有人共享同样问题后，我重新下载了64位的jdk进行了安装），64位的jdk安装后，一般能解决上述问题。

望对遇到上述问题的朋友有帮助

4、   编译成功信息
