1.ubuntu，hadoop，R，jdk安装好
2.下载Rhadoop项目的的三个包，rmr，hdfs，rHBase存放到Downloads/R。
3.切换到root
4.安装依赖的库
~R CMD javareconf
~R
>install.packages("rJava")
reshape2,Rcpp,iterators,itertools,digest,RJSONIO,functional
5.安装rhdfs库
环境变量
export JAVA_HOME=/home/csf/Downloads/jdk1.8.0_31
HADOOP_CMD=/home/csf/Downloads/hadoop/bin/hadoop
HADOOP_STREAMING=/home/csf/Downloads/hadoop/share/hadoop/tools/lib/hadoop-streaming-2.2.0.jar

7.确保安装所有的库
这里Rcpp没有安装成功，折腾了半天，
使用下面这个命令删除了Rcpp的相关文件夹
