Como faço para instalar o Rhadoop do Github usando Devtools
Basicamente, estou querendo instalar rhdfs de https://github.com/RevolutionAnalytics/rhdfs
mas isso não funciona
Eu tentei o seguinte
> install_github("https://github.com/RevolutionAnalytics/rhdfs")
Error in username %||% getOption("github.user") %||% stop("Unknown username.") :
Unknown username.
> install_git("https://github.com/RevolutionAnalytics/rhdfs")

Você pode baixar e instalar os pacotes Rhadoop aqui
https://github.com/RevolutionAnalytics/RHadoop/wiki/Downloads
rhdfs tem alguns pré-requisitos
https://github.com/RevolutionAnalytics/RHadoop/wiki/user%3Erhdfs%3EHome
Prerequisites
This package has a dependency on rJava
Access to HDFS via this R package is dependent upon the HADOOP_CMD environment variable. HADOOP_CMD points to the full path for the hadoop binary. If this variable is not properly set, the package will fail when the init() function is invoked
Example:
HADOOP_CMD=/usr/bin/hadoop
