Michael Sannella x268 4a9e03fa85 [SPARK-8019] [SPARKR] Support SparkR spawning worker R processes with a command other then Rscript ... This is a simple change to add a new environment variable "spark.sparkr.r.command" that specifies the command that SparkR will use when creating an R engine process. If this is not specified, "Rscript" will be used by default. I did not add any documentation, since I couldn't find any place where environment variables (such as "spark.sparkr.use.daemon") are documented. I also did not add a unit test. The only test that would work generally would be one starting SparkR with sparkR.init(sparkEnvir=list(spark.sparkr.r.command="Rscript")), just using the default value. I think that this is a low-risk change.
