Hi Jeff Initially, we used the Spark version that defined by the Zep 0.9.0 and got the error. When we changed the Spark to the latest version 3.1.2, we got a different error. Fyi, we are not using Spark at all, but it seems the R interpreter has dependency on the SparkR. Our requirement is to enable R interpreter with the latest R version. Please advice. Thanks. > .libPaths(c(file.path(libPath), .libPaths())) > library(SparkR) Error in readRDS(pfile) : unknown input format Calls: library -> find.package -> lapply -> FUN -> readRDS Execution halted
