CentOS6.5实现Hadoop编译
Hadoop 2.x 三大组件
MapReduce(Others) -- 计算
YARN -- 资源和作业调度平台
HDFS -- 存储
环境准备：
[root@hadoop001 software]# pwd
/opt/software

1.Hadoop源代码下载
[root@hadoop001 software]# tar -xzvf hadoop-2.8.1-src.tar.gz
# 检查源码包环境
[root@hadoop001 hadoop-2.8.1-src]# cat BUILDING.txt
----------------------------------------------------------------------------------
Requirements:
* Unix System
* JDK 1.7+
* Maven 3.0 or later
* Findbugs 1.3.9 (if running findbugs)
* ProtocolBuffer 2.5.0
* CMake 2.6 or newer (if compiling native code), must be 3.0 or newer on Mac
* Zlib devel (if compiling native code)
* openssl devel (if compiling native hadoop-pipes and to get the best HDFS encryption performance)
* Linux FUSE (Filesystem in Userspace) version 2.6 or above (if compiling fuse_dfs)
* Internet connection for first build (to fetch all Maven and Hadoop dependencies)
2.JAVA安装

[root@hadoop001 ~]# mv jdk-8u45-linux-x64.gz /usr/java
[root@hadoop001 ~]# cd /usr/java
[root@hadoop001 ~]# tar -xzvf jdk-8u45-linux-x64.gz
# 修改用户和用户组
