Steve Loughran commented on HADOOP-5772:
----------------------------------------
I think reloading is separate from distributed sourcing of configuration . You
can have a distributed source of configuration that isn't
reloaded/read-on-demand; you can even reload stuff from the local (or
NFS-mounted) FS
> Implement a 'refreshable' configuration system with right access-controls etc.

> URL: https://issues.apache.org/jira/browse/HADOOP-5772
> Project: Hadoop Core
> Issue Type: New Feature
> Components: conf
> Reporter: Arun C Murthy

> We have various bits and pieces of code to refresh certain configuration
> files, various components to restrict access to who can actually refresh the
> configs etc.
> I propose we start thinking about a simple system to support this as a
> first-class citizen in Hadoop Core...
