Description
Ideally, defaults files should only contain name / value pairs (as per Debian packaging policy), which makes it difficult for a cluster management system that may be managing Hadoop to control the environment when these files are sources and variables are perhaps exported into the environment unconditionally.
In keeping with Bigtop's goal if integrating Hadoop with the underlying operating system, the default behavior should not change at all, but it would provide greater flexibility if there was a mechanism to disable the sourcing of files so that if a system wants the environment variables to be used exclusively, the defaults files won't override that behavior.
Obviously since this may be a more rare use case right now, the solution should also be as safe and non-disruptive as possible.
