Subject [jira] [Commented] (YARN-6492) Generate queue metrics for each partition
Date Thu, 12 Oct 2017 04:49:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-6492?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16201432#comment-16201432

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

Sorry for the delay. Had a offline discussions with [~Naganarasimha] & [~sunilg] regarding
the structure and POC patch to deliver the same. It has taken a shape and attached JMX o/p
for further discussions. Attached o/p has 1. PartitionQueueMetrics and  2. QueueMetrics. 

1. For POC, We had two partitions, x & y. Hence o/p will have PartitionQueueMetrics for
both the partitions. Under each PartitionQueueMetrics, QueueMetrics for each queue and UserMetrics
for each user would be available.

2. We have retained  existing QueueMetrics for backward compatiblity which also has been captured
in o/p for better understanding.

[~jlowe] [~jhung] [~sunilg] Thoughts?

> 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.
