[jira] [Commented] (YARN-4160) Dynamic NM Resources Configuration
file should be simplified.
[ https://issues.apache.org/jira/browse/YARN-4160?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14803112#comment-14803112 ]
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.

> 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.
