我需要将安装在Windows 7中的Tableau连接到我在Cloudera VM中运行的R。我已经安装了R中Rserve包装和R端子运行这些命令：将R与Tableau连接
> library(Rserve)
> Rserve
当我试图连接至R中的Tableau我收到以下错误：
External Service: An error has occurred during connection to xxx.xxx.xxx.xxx:6311: No connection could be made because the target machine actively refused it ExtSvc: Couldn't connect to server
我曾与127.0.0.1尝试，虚拟机的IP以及安装的Cloudera ODBC驱动程序。
