Manikandan R commented on YARN-6492:
------------------------------------
[~jhung] Thanks for your comments.
{quote}What's the rationale behind having a separate PartitionQueueMetrics
metrics info?{quote}
Currently as of now we have been following "Partition->Queue" hierarchy in UI
and scheduling as well. To ensure that we have similar hierarchy even in JMX
metrics and also helps users/admins to have a better understanding about the
usage.
{quote}s it possible to factor the partition metrics to QueueMetrics class
similar to how user metrics is implemented? (i.e. have some configuration to
enable partition metrics, and register a new QueueMetrics with the partition
tag){quote}
Yes, thats the plan. We will do this while implementing the same.
{quote}Also the existing metrics for PartitionQueueMetrics in the attachment
only has pendingMB, pendingVCores, pendingContainers. Will this be filled out
to match the set of metrics supported by the current queue metrics?
(appsSubmitted, appsFailed, allocatedMB, availableMB, ...){quote}
Yes. Earlier attached o/p was to detail out the structure to help us in better
understanding for further discussions purpose. While doing the implementation,
we will cover all the existing metrics.

> 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.
