> "Packages should not write in the users’ home filespace, nor anywhere else on the file system apart from the R session’s temporary directory (or during installation in the location pointed to by TMPDIR: and such usage should be cleaned up). Installing into the system’s R installation (e.g., scripts to its bin directory) is not allowed.
> Limited exceptions may be allowed in interactive sessions if the package obtains confirmation from the user.
> - Packages should not modify the global environment (user’s workspace)."
> Currently "spark-warehouse" gets created in the working directory when sparkR.session() is called.
