在 ~/.bashrc 文件中添加这三行.

*export HADOOP_PREFIX=/Users/hadoop/hadoop-1.1.2

*export HADOOP_PREFIX=/Users/hadoop/hadoop-1.1.2

导出 HADOOP_CMD=/Users/hadoop/hadoop-1.1.2/bin/hadoop

export HADOOP_CMD=/Users/hadoop/hadoop-1.1.2/bin/hadoop

导出 HADOOP_STREAMING=/Users/hadoop/hadoop-1.1.2/contrib/streaming/hadoop-streaming-1.1.2.jar*

export HADOOP_STREAMING=/Users/hadoop/hadoop-1.1.2/contrib/streaming/hadoop-streaming-1.1.2.jar*

使用此命令安装 R 包

推荐答案

从 https://github.com/RevolutionAnalytics/RHadoop/wiki 并按如下方式安装它们:

Download packages rhdfs, rhbase, rmr2 and plyrmr from https://github.com/RevolutionAnalytics/RHadoop/wiki and install them as below :

install.packages("<path>/rhdfs_1.0.8.tar.gz", repos=NULL, type="source")
install.packages("<path>/rmr2_2.2.2.tar.gz", repos=NULL, type="source")
install.packages("<path>plyrmr_0.2.0.tar.gz", repos=NULL, type="source")
install.packages("<path>/rhbase_1.2.0.tar.gz", repos=NULL, type="source")
