>
> Apache Hadoop’s RunJar.run() does not set permissions for temporary directory
> by default. If sensitive data will be present in this file, all the other
> local users may be able to view the content.
> This is because, on unix-like systems, the system temporary directory is
> shared between all local users. As such, files written in this directory,
> without setting the correct posix permissions explicitly, may be viewable by
> all other local users.
