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

6.

csf@ubuntu:~/Downloads/hadoop$ . /etc/environment

csf@ubuntu:~/Downloads/hadoop$ cd ..

csf@ubuntu:~/Downloads$ R CMD INSTALL /R/rhdfs_1.0.8.tar.gz

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

8.重新安装plyr,reshape2等
