Hadoop-2.x的源码编译

由于在Hadoop-2.x中，Apache官网上提供的都是32位版本，如果是生产环境中则需要自行编译64位，编译Hadoop-2.x版本方法如下：

安装编译源码所依赖的底层库
　　yum install glibc-headers
　　yum install gcc
　　yum install gcc-c++
　　yum install make
　　yum install cmake
　　yum install openssl-devel
　　yum install ncurses-devel

安装protobuf-2.5.0（Hadoop中节点间的RPC通讯协议的实现是基于Google的Protocol buffer）
　　tar -zxvf /home/tools/protobuf-2.5.0.tar.gz -C /home/tools/
　　cd protobuf-2.5.0 && ./configure && make && make check && make install

安装apache-maven-3.0.5（这里我安装的JDK1.7，编译Hadoop源码时需要使用maven）
　　tar -zxvf /home/tools/apache-maven-3.0.5-bin.tar.gz -C /home/tools/
　　vi /etc/profile
　　export JAVA_HOME=/usr/local/java
　　export M2_HOME=/usr/local/apache-maven-3.0.5
　　export PATH=.:$M2_HOME/bin:$JAVA_HOME/bin:$PATH

解压Hadoop-2.4.1-src.tar.gz源码包进行编译
　　tar -zxvf /home/tools/hadoop-2.4.1-src.tar.gz -C /home/tools/
　　cd /home/tools/hadoop-2.4.1-src
　　mvn package -DskipsTests -Pdist,native
　　出现如下日志表示编译成功
