    @andrewor14, 
    I have tested this patch with a real YARN cluster. 
    
    For an R program, it can source other R files and call functions within them, or it can
call functions exposed in other R packages. For sourcing R files, it can be supported via
the existing --files (refer to SPARK-6833). For dependent R packages, SparkR now only supports
passing the name list of the R packages to workers, but not distributing the packages themselves.
It is expected that they are already installed in the R environment on worker nodes. Not sure
if we support distributing dependent R packages or not, @shivaram, what do you think?
