Build instructions for Hadoop
----------------------------------------------------------------------------------
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

yum install -y snappy snappy-devel bzip2 bzip2-devel lzo lzo-devel lzop autoconf automake
7.编译
[root@testdb sourcecode]# cd hadoop-2.8.1-src
[root@testdb sourcecode]# mvn clean package -Pdist,native -DskipTests -Dtar
8.tar
/opt/sourcecode/hadoop-2.8.1-src/hadoop-dist/target/hadoop-2.8.1.tar.gz
提醒：
1、有时候编译过程中会出现下载某个包的时间太久，这是由于连接网站的过程中会出现假死，
此时按ctrl+c，重新运行编译命令。
2、如果出现缺少了某个文件的情况，则要先清理maven(使用命令 mvn clean) 再重新编译。
