[jira] [Commented] (YARN-6492) Generate queue metrics for each partition

["Eric Payne (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-6492?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16903050#comment-16903050 ] 

Eric Payne commented on YARN-6492:
----------------------------------

Hi [~manirajv06@gmail.com]. Thanks for the updated patch.

I see that in the {{jmx?qry=Hadoop:*}} response, the word "default" is used to represent the DEFAULT_PARTITION. For example:
{panel}
...
"name": "Hadoop:service=ResourceManager,name=PartitionQueueMetrics,p0=default"
...
"tag.Partition": "default"
{panel}
In order to be consistent with other API responses like {{/ws/v1/cluster/scheduler}}, I think this should just be an empty string. So, I would expect the JMX response to look like the following for DEFAULT_PARTITION:
{panel}
...
"name": "Hadoop:service=ResourceManager,name=PartitionQueueMetrics,p0="
...
"tag.Partition": ""
{panel}

> We are interested in having queue metrics for all partitions. Right now each queue has one QueueMetrics object which captures metrics either in default partition or across all partitions. (After YARN-6467 it will be in default partition)
> But having the partition metrics would be very useful.
