there's a way, but overall we do not exit/terminate the R session since
SparkR could be running in an interactive session (eg. RStudio)
one possible approach is to exit only when running sparkR shell, by
checking here:
https://github.com/apache/spark/blob/master/R/pkg/inst/profile/shell.R#L27
I'm not sure if stop() vs exit makes much of a difference though.
