Kenji Kikushima updated YARN-1000:
----------------------------------
Attachment: YARN-1000-sample.patch
Attached file is sample implementation to switch dynamic resource configuration
on RM.
This patch introduces "yarn.dynamic-resource-configuration.enable" and
"yarn.dynamic-resource-configuration-persist.enable" parameters.
Please refer to it if you have interest. I'm okay that leave it until proper
timing. Thanks.

> There are some configurations for feature of dynamic resource configuration:
> 1. enable or not: if enable, then setting node resource in runtime through
> CLI/REST/JMX can be successful, else exceptions of "function not supported"
> will be thrown out. In future, we may support to enable this feature in
> partial nodes which has resource flexibility (like virtual nodes).
> 2. dynamic resource setting is persistent or not: it depends on users'
> scenario to see if the life cycle of setting in runtime should be kept after
> NM is down and restart.
