> As of SPARK-6797, sparkr.zip is re-created each time spark-submit is run with an R application,
which fails if Spark has been installed into a directory to which the current user doesn't
have write permissions. (e.g., on EMR's emr-4.0.0 release, Spark is installed at /usr/lib/spark,
which is only writable by root.)
> Would it be possible to skip creating sparkr.zip if it already exists? That would enable
sparkr.zip to be pre-created by the root user and then reused each time spark-submit is run,
which I believe is similar to how pyspark works.
> Another option would be to make the location configurable, as it's currently hardcoded
to $SPARK_HOME/R/lib/sparkr.zip. Allowing it to be configured to something like the user's
home directory or a random path in /tmp would get around the permissions issue.
> By the way, why does spark-submit even need to re-create sparkr.zip every time a new
R application is launched? This seems unnecessary and inefficient, unless you are actively
developing the SparkR libraries and expect the contents of sparkr.zip to change.
