> Issue Type: Improvement

> Currently Hadoop's RunJar will unjar the jar provided and look for any jars
> inside and add them to the classpath. Since most deployments doesn't use jar
> in jar, but rather uberjars this could be rather time consuming at times and
> can cause issues related to over consumption of inodes, for something that is
> in many cases is not used.
> For that purpose there should be an env variable to disable this behavior.
