Rstudio-server环境变量未加载？ [英] Rstudio-server environment variables not loading?

问题描述

我试图在Cloudera的hadoop发行版上运行rhadoop（我不记得它的CDH3或4），并且遇到了一个问题：Rstudio服务器似乎无法识别我的全局变量。

在我的/etc/profile.d/r.sh文件中，我有：

  export HADOOP_HOME = / usr / lib / hadoop 
 export HADOOP_CONF = / usr / hadoop / conf 
 export HADOOP_CMD = / usr / bin / hadoop 
 export HADOOP_STREAMING = / usr / lib / hadoop -mapreduce / 
  

当我从终端运行R时，我得到：

 > Sys.getenv（HADOOP_CMD）
 [1]usr / bin / hadoop
  

但是当我运行Rstudio服务器时：

 > Sys.getenv（HADOOP_CMD）
 [1]
  

，当我尝试运行rhdfs时：

 >库（rJava，lib.loc =/ home / cloudera / R / x86_64-redhat-linux-gnu-library / 2.15）
>库（rhdfs，lib.loc =/ home / cloudera / R / x86_64-redhat-linux-gnu-library / 2.15）
错误：.onLoad在'rhdfs'的loadNamespace（） ：
 call：fun（libname，pkgname）
错误：在加载程序包之前必须设置环境变量HADOOP_CMD 
错误：'rhdfs'
包/名称空间加载失败code> 

有没有人知道我应该把我的环境变量放在哪里，如果不在特定的r.sh文件中？

感谢！

您应该在中设置您的环境变量。 Renviron 或 Renviron.site 。我认为这些文件是在 R_HOME / etc / Renviron.site 下定义的。您可以输入以下内容获取更多信息：

 > ？启动
  

有人有类似的问题这里，这是他解决它的方法。

I'm trying to run rhadoop on Cloudera's hadoop distro (I can't remember if its CDH3 or 4), and am running into an issue: Rstudio server doesn't seem to recognize my global variables.

In my /etc/profile.d/r.sh file, I have:

export HADOOP_HOME=/usr/lib/hadoop
export HADOOP_CONF=/usr/hadoop/conf
export HADOOP_CMD=/usr/bin/hadoop
export HADOOP_STREAMING=/usr/lib/hadoop-mapreduce/

When I run R from the terminal, I get:

> Sys.getenv("HADOOP_CMD")
[1] "usr/bin/hadoop"

But when I run Rstudio server:

> Sys.getenv("HADOOP_CMD")
[1] ""

And as a result, when I try to run rhdfs:

> library("rJava", lib.loc="/home/cloudera/R/x86_64-redhat-linux-gnu-library/2.15")
> library("rhdfs", lib.loc="/home/cloudera/R/x86_64-redhat-linux-gnu-library/2.15")
Error : .onLoad failed in loadNamespace() for 'rhdfs', details: 
    call: fun(libname, pkgname)
    error: Environment variable HADOOP_CMD must be set before loading package rhdfs
Error: package/namespace load failed for 'rhdfs'

Does anyone know where I should be putting my enviornment variables if not in that specific r.sh file?

Thanks!

解决方案

You should set your environment variables in .Renviron or Renviron.site. I think these files are defined under R_HOME/etc/Renviron.site. You can get more information by typing:

> ?Startup

Someone had a similar issue here and this is what he did to solve it.
