Linux环境下编译hadoop2.4

1、jdk的安装

...

检验是否安装成功 java -version、java、javac

2、maven的安装

...

验证安装是否成功   mvn -version

3、protobuf的安装

（0） 安装gcc

#方法一：
sudo apt-get  build-depgcc

#方法二：
sudo apt-get  install  build-essential

#验证安装：
gcc --version

（1）下载

1. sudo wget https://protobuf.googlecode.com/files/protobuf-2.5.0.tar.gz

 （2）安装：

然后进入protobuf-2.5.0文件夹，进行如下操作：

$ sudo ./configure
$ sudo make
$ sudo make check
$ sudo make install
$ sudo ldconfig

（3）验证

protoc --version

4.安装openssl库

1. sudo apt-get install libssl-dev

5.CMake安装

1. sudo apt-get install cmake

6.ant安装

（1）首先下载ant

（2）解压

1. tar zxvf apache-ant-1.9.4-bin.tar.gz

 (3)配置环境变量

source /etc/profile

（4）.检验安装成功

1. ant -version

二、编译hadoop2.4

上面准备工作已经做的差不多了，进入hadoop-src/文件夹下，输入下面命令

mvn package -Pdist,native -DskipTests -Dtar

等了40多分钟，ok

在目录~/hadoop-2.4.0-src/hadoop-dist/target下有文件：
hadoop-2.4.0.tar.gz

问题总结：

这里还需要在补充：
1.遇到错误1：CMake没有安装

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-
plugin:1.6:run (make) on project hadoop-common: An Ant BuildException has
occured: Execute failed: java.io.IOException: Cannot run program "cmake" (in

解决方法：

CMake没有安装

1. sudo apt-get install cmake

2.遇到错误2：ant没有安装

解决：

   安装ant。

3.protobuf版本过低，错误现象

hadoop2.4对应的版本是protobuf-2.5.0

解决办法：

按照安装步骤中protobuf-2.5.0的安装即可
