Brendan Dwyer created SPARK-18817:
-------------------------------------
Summary: Ensure nothing is written outside R's tempdir() by default
Key: SPARK-18817
URL: https://issues.apache.org/jira/browse/SPARK-18817
Project: Spark
Issue Type: Sub-task
Components: SparkR
Reporter: Brendan Dwyer
Per CRAN policies
https://cran.r-project.org/web/packages/policies.html
"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.
