> There should be a way to dynamically reload the configuration properties from
> the disk. The approach is to notify the individual classes that the
> Configuration is reloaded and make the changes on the fly. The purpose of
> this feature is to let individual classes which are interested in observing
> this configuration changes, to be notified when the conf is reloaded from the
> desk. This is similar to how Hbase has done.
