Description

Hi expert,

I try to use livy to connect sparkR backend.

This is related to https://stackoverflow.com/questions/53900995/livy-spark-r-issue

 

Error message is,

Error in sparkR.sparkContext(master, appName, sparkHome, sparkConfigMap, : Auth secret not provided in environment.

 

caused by,

spark-2.3.1/R/pkg/R/sparkR.R

sparkR.sparkContext <- function(

...

    authSecret <- Sys.getenv("SPARKR_BACKEND_AUTH_SECRET")
    if (nchar(authSecret) == 0) {
      stop("Auth secret not provided in environment.")
    }

...

)

 

Best regard.
