> Utility to dynamically reload Configuration on the disk
> -------------------------------------------------------
>
> Key: YARN-10216
> URL: https://issues.apache.org/jira/browse/YARN-10216
> Project: Hadoop YARN
> Issue Type: New Feature
> Reporter: Cyrus Jackson
> Assignee: Cyrus Jackson
> Priority: Major
> Attachments: YARN-10216.001.patch, image-2020-04-06-09-50-51-948.png
>
>
> There should be a way to dynamically reload the configuration properties from
> the disk. 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 disk. This is similar to how Hbase has done.
> *Class Diagram*
> !image-2020-04-06-09-50-51-948.png!
>
> *APPROACH DETAILS*
> The approach is based on the adaption of Hbase Online Configuration. In this
> case, the configuration file is monitored for any changes on the disk. If the
> file has changed, the properties of Configuration is reloaded and all the
> observers are notified.
> The classes that implements the observers updates the necessary values if
> required.
