[jira] [Commented] (YARN-6224) Should consider utilization of each
ResourceType on node while scheduling
[ https://issues.apache.org/jira/browse/YARN-6224?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17239571#comment-17239571 ]

It's a good policy to choose node based dominant node resource, when with more and more resource type in our production cluster, such as GPU/FPGA etc.

> Key: YARN-6224
> URL: https://issues.apache.org/jira/browse/YARN-6224
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Tao Jie
> Priority: Major
>
> In situation like YARN-6101, if we consider all type of resource(vcore, memory) utilization on node rather than just answer we can allocate or not, we are more likely to have better resource utilization as a whole.
> It is possible that we have a set of candidate nodes, then find the most promising node to assign to one request considering node resource utilization with global scheduling.
