Subject [jira] [Commented] (YARN-6492) Generate queue metrics for each partition
Date Wed, 24 Jan 2018 17:22:02 GMT

    [ https://issues.apache.org/jira/browse/YARN-6492?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16337911#comment-16337911
] 

Manikandan R commented on YARN-6492:
------------------------------------

Attaching WIP patch for high level review based on earlier comments focusing mainly to following
items:

1. Incorporating PartitionQueueMetrics computation in QueueMetrics class itself
2. Avoid using "enablePartitionMetrics" and use "default" for default partition.

> 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.
