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.

Error in readRDS(pfile) : unknown input format
Calls: library -> find.package -> lapply -> FUN -> readRDS
Execution halted

What version of spark do you use ? I am not sure whether your spark version
supports R 4.0 ?
