在网上搜了一篇博客，然后按照上面的步骤进行操作，
http://blog.csdn.net/linlinv3/article/details/49358217
遇到的问题：
1、java版本：一定要jdk7,不能是jdk8，否则报错.提示java版本有问题。
2、安装protoc ， ./configure –prefix=/usr/local/protoc/ ;
make; make install ;

protoc –version 只有显示版本信息才表示安装成功。若没有显示，则在编译hadoop时，会提示找不到protoc命令。
注意要配置成环境变量：
export PATH=/usr/local/protoc/bin:$PATH
3、在编译protoc时，就已经进行过make，make install后，再次执行make，会报错
libtool: install: error: cannot install `libaprutil-1.la’ to a directory

执行 make clean，重新解压，再编译即可。
以前觉得编译hadoop时很高大上的事情，现在自己开始编译，发现也没啥（可能是我运气好）。
网络是否稳定。

纪念一下： 从17:33-20:51,总算编译成功了，下载的jar包有
133M /root/.m2/repository
期间包括下载jdk，换jdk版本；重新编译 protoc；还算顺利。
