2. 安装Rhadoop
安装rhdfs，rmr2
cd Rhadoop/
R CMD javareconf
R CMD INSTALL 'plyr_1.8.tar.gz'
R CMD INSTALL 'stringr_0.6.2.tar.gz'
R CMD INSTALL 'reshape2_1.2.2.tar.gz'
R CMD INSTALL 'digest_0.6.3.tar.gz'
R CMD INSTALL 'functional_0.4.tar.gz'
R CMD INSTALL 'iterators_1.0.6.tar.gz'
R CMD INSTALL 'itertools_0.1-1.tar.gz'
R CMD INSTALL 'Rcpp_0.10.3.tar.gz'
R CMD INSTALL 'rJava_0.9-4.tar.gz'
R CMD INSTALL 'RJSONIO_1.0-3.tar.gz'
R CMD INSTALL 'reshape2_1.2.2.tar.gz'
R CMD INSTALL 'rhdfs_1.0.5.tar.gz'
R CMD INSTALL 'rmr2_2.2.0.tar.gz'
R library(rhdfs)检查是否能正常工作
验证测试
Rmr测试命令：
> train.mr<-mapreduce( + train.hdfs, + map = function(k, v) { + keyval(k,v$item) + } + ,reduce=function(k,v){ + m<-merge(v,v) + keyval(m$x,m$y) + } + )
出现如下错误：
packageJobJar: [/tmp/RtmpCuhs7d/rmr-local-env18916b6f86b3, /tmp/RtmpCuhs7d/rmr-global-env18913824c681, /tmp/RtmpCuhs7d/rmr-streaming-map18912d6c2b1c, /tmp/RtmpCuhs7d/rmr-streaming-reduce1891179bb645, /tmp/hadoop-root/hadoop-unjar4575094085541826184/] [] /tmp/streamjob2910108622786868147.jar tmpDir=null 13/06/05 18:22:28

错误解决方法： 通过查看日志，hadoop没有在/usr/bin下找到Rscript,于是从R的安装目录/usr/local/bin下做R和Rscript的符号链接到/usr/bin下，再次执行即可解决次错。
#ln -s /usr/loca/bin/R /usr/bin
#ln -s /usr/local/bin/Rscript /usr/bin
3. 安装rhbase
## 安装依赖
#yum install boost*
#yum install openssl*
安装thrift
#tar -zxvf thrift-0.9.0.tar.gz
#mv thrift-0.9.0/lib/cpp/src/thrift/qt/moc_TQTcpServer.cpp thrift-0.9.0/lib/cpp/src/thrift/qt/moc_TQTcpServer.cpp.bak
#cd thrift-0.9.0
#./configure --with-boost=/usr/include/boost JAVAC=/usr/java/jdk1.6.0_31/bin/javac
#make
#make install
如果报错：error: “Error: libcrypto required.”
#yum install openssl*
如果报错：
src/thrift/qt/moc_TQTcpServer.cpp:14:2: error: #error "This file was generated using the moc from 4.8.1. It"
src/thrift/qt/moc_TQTcpServer.cpp:15:2: error: #error "cannot be used with the include files from this version of Qt."
src/thrift/qt/moc_TQTcpServer.cpp:16:2: error: #error "(The moc has changed too much.)"
则运行下面命令：
#mv thrift-0.9.0/lib/cpp/src/thrift/qt/moc_TQTcpServer.cpp thrift-0.9.0/lib/cpp/src/thrift/qt/moc_TQTcpServer.cpp.bak
配置PKG_CONFIG_PATH
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig/
pkg-config --cflags thrift #返回：-I/usr/local/include/thrift为正确
cp /usr/local/lib/libthrift-0.9.0.so /usr/lib/
cp /usr/local/lib/libthrift-0.9.0.so /usr/lib64/
启动hbase：
/usr/lib/hbase/bin/hbase-daemon.sh start thrift
使用jps查看thrift进程
安装rhbase
R CMD INSTALL 'rhbase_1.1.1.tar.gz'
验证并测试
在R命令行中输入library(rmr2)、library(rhdfs)、library(rhbase)，载入成功即表示安装成功

4. 装RHive
环境变量
设置环境变量 vim /etc/profile,末行添加如下：
export HADOOP_CMD=/usr/bin/hadoop
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/
export HADOOP_STREAMING=/usr/lib/hadoop-0.20-mapreduce/contrib/streaming/hadoop-streaming-2.0.0-mr1-cdh4.2.1.jar
export HADOOP_HOME=/usr/lib/hadoop
export RHIVE_DATA=/hadoop/dfs/rhive/data
export HIVE_HOME=/usr/lib/hive
安装Rserve：
#R CMD INSTALL 'Rserve_1.7-1.tar.gz'
在安装Rsever用户下，创建一目录，并创建Rserv.conf文件，写入``remote enable’‘保存并退出。
#cd /usr/local/lib64/R/
#echo remote enable > Rserv.conf
启动Rserve：
#R CMD Rserve --RS-conf /usr/local/lib64/R/Rserv.conf
检查Rserve启动是否正常：
#telnet localhost 6311
显示 Rsrv0103QAP1 则表示连接成功
安装RHive
创建数据目录：
#R CMD INSTALL RHive_0.0-7.tar.gz
#cd /usr/local/lib64/R/
mkdir -p rhive/data
在上传rhive_udf.jar到hdfs上：
hadoop fs -mkdir /rhive/lib
cd /usr/local/lib64/R/library/RHive/java
hadoop fs -put rhive_udf.jar /rhive/lib
hadoop fs -chmod a+rw /rhive/lib/rhive_udf.jar
cd /usr/lib/hadoop
ln -s /etc/hadoop/conf conf
测试RHive安装是否成功：
R
library（RHive）
rhive.connect('192.168.0.27')【hive的地址】
rhive.env()
