Junping Du commented on YARN-4160:
----------------------------------

The proposed new configuration is as following:
{noformat}
<Configuration>
  <NodeResource>
    <NodeId> node_1, node_2, node_3</NodeId>
    <vcore> 1 </vcore>
    <memory> 1024 </memory>
  </NodeResource>

  <NodeResource>
    <NodeId> node_4, node_5</NodeId>
    <vcore> 2 </vcore>
    <memory> 2048 </memory>
  </NodeResource>
</Configuration>

{noformat}
Any comments?
btw, NodeID can be Host:Port or Host only for user's convenient.

> Dynamic NM Resources Configuration file should be simplified.

> In YARN-313, we provide CLI to refresh NMs' resources dynamically. The format 
> of dynamic-resources.xml is something like following:
> {noformat}
> <configuration>
>   <property>
>     <name>yarn.resource.dynamic.node_id_1.vcores</name>
>     <value>16</value>
>   </property>
>   <property>
>     <name>yarn.resource.dynamic.node_id_1.memory</name>
>     <value>1024</value>
>   </property>
> </configuration>
> {noformat}
> This looks too redundant from review comments of YARN-313. We should have a 
> better, concisely format.
