[root@rzdatahadoop001 hadoop-2.8.1-src]# 

download需要3.5h
不想download就使用.m2.tar.gz -->解压-->root家目录

8.编译好的tar包
 /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。
