Sean Mackrory updated BIGTOP-1037:
----------------------------------
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.
