光说不练假把式。撸起袖子干起来！本文就是学习。。。。。。选用 hadoop-2.4.0
第一步：必要环境准备
yum install cmake lzo-devel zlib-devel gcc gcc-c++ autoconf automake libtool ncurses-devel openssl-devel libXtst前4个解压之后需要配置到 /etc/profile，这个就不用多说了。。。
| 序号 | 名称 | 版本 | 下载路径 | 安装路径 |
|---|---|---|---|---|
| 1 | java | 1.8.0 | http://download.oracle.com/otn-pub/java/jdk/8u151-b12/e758a0de34e24606bca991d704f6dcbf/jdk-8u151-linux-x64.tar.gz | /usr/local/jdk1.8.0 |
| 2 | maven | 3.3.9 | https://archive.apache.org/dist/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz | /usr/local/apache-maven-3.3.9 |
| 3 | apache-ant | 1.9.9 | https://archive.apache.org/dist/ant/binaries/apache-ant-1.9.9-bin.tar.gz | /usr/local/apache-ant-1.9.9 |
| 4 | findbugs | 3.0.1 | http://prdownloads.sourceforge.net/findbugs/findbugs-3.0.1.tar.gz?download | /usr/local/findbugs-3.0.1 |
| 5 | protobuf | 2.5.0 | https://github.com/google/protobuf/releases/download/v2.5.0/protobuf-2.5.0.tar.gz | 需要编译安装 |
检查是否安装成功：
1.1 protobuf安装：
1.解压 ：
tar -zxvf protobuf-2.5.0.tar.gz 2.编译安装：
进入解压后的protobuf-2.5.0目录：
[root@localhost protobuf-2.5.0]# ./config
[root@localhost protobuf-2.5.0]# make
[root@localhost protobuf-2.5.0]# make install3.检查是否安装成功：
[root@localhost protobuf-2.5.0]# protoc --version
第二步：将32位编译成64位本地库
2.1 解压tar.gz
[root@localhost ~]# tar -zxvf hadoop-2.4.0-src.tar.gz 2.2 进入已解压的目录
[root@localhost ~]# cd hadoop-2.4.0-src
[root@localhost hadoop-2.4.0-src]# pwd
/root/hadoop-2.4.0-src
[root@localhost hadoop-2.4.0-src]# 2.3 执行maven编译命令
[root@localhost hadoop-2.4.0-src]# mvn clean install -Dmaven.test.skip=true2.4 执行maven打包命令
[root@localhost hadoop-2.4.0-src]# mvn package -Pdist,native -DskipTests -Dtar
出现错误：使用jdk1.8语法造成的

如上图所示，表示成功编译位64位hadoop-2.4.0到本地库。
以上就是全文的内容，由于水平有限，文章中难免会有错误，希望大家指正。谢谢~
