Hi dev list, SparkR backend assumes SparkR source files are located under "SPARK_HOME/R/lib/." This directory is created by running R/install-dev.sh. This setting makes sense for Spark developers, but if an R user downloads and installs SparkR source package, the source files are going to be in placed different locations.
In the R runtime it is easy to find location of package files using path.package("SparkR"). But we need to make some changes to R backend and/or spark-submit so that, JVM process learns the location of worker.R and daemon.R and shell.R from the R runtime. Do you think this change is feasible? Thanks, --Hossein
