Kenji Kikushima updated YARN-998:
---------------------------------
Attachment: YARN-998-sample.patch
Attached file is sample implementation to persist ResourceOption on RM.
Please refer to it if you have interest. I'm okay that leave it until proper
timing. Thanks.

- Sorry this patch supports RM restart only
- It possibly affect scalability on large cluster because of using XML to
persist ResourceOption
