Question

我一直在使用Pentaho和一个基本的R脚本创建一个简单的转换。它引入一个由2列a，b和3个条目组成的CSV全部整数。数据预览与数据相同。

R脚本是该过程的核心，如下所示：

c <- a+b
OUTPUT <-list("c"=c)

流程如下：

CSV_FILE_INPUT ->- Exceute_R_Script ->- Select_Values

Answer 1

要跟踪错误，可以在没有GUI的情况下启动转换，但使用命令行工具pan.bat。例如：

 pan.bat /rep:"Production Repository"
            /trans:"update Customer Dimension"
            /dir:/Dimensions/
            /user:matt
            /pass:somepassword123
            /level:Basic

此问题的解决方案是指定R_HOME环境变量，如：

R_HOME=C:\Program Files\R\R-3.1.2

但不为

R_HOME=C:\Program Files\R\R-3.1.2*bin\x64*

Pentaho在启动R脚本后退出
