Subject [jira] [Commented] (YARN-4304) AM max resource configuration per partition to be displayed/updated correctly in UI and in various partition related metrics
Date Mon, 04 Jan 2016 21:20:40 GMT

    [ https://issues.apache.org/jira/browse/YARN-4304?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15081826#comment-15081826
] 

Wangda Tan commented on YARN-4304:
----------------------------------

1) REST response: amResourceLimit -> amLimit (it's a part of resources, so don't need to
mention it's a resource)
2) REST response: for parent queue, queueCapacitiesByPartition contains maxAMLimitPercentage
and resourceUsagesByPartition contains amResourceLimit. I would suggest to add a flag to include
am-resource-related fields by queueCapacitiesByPartition/resourceUsagesByPartition only when
a queue is leaf queue.
3) I'm not sure if it's possible that user's am limit could be greater than queue's am limit,
we should cap user's am limit by queue's am limit.

> As we are supporting per-partition level max AM resource percentage configuration, UI
and various metrics also need to display correct configurations related to same. 
> For eg: Current UI still shows am-resource percentage per queue level. This is to be
updated correctly when label config is used.
> - Display max-am-percentage per-partition in Scheduler UI (label also) and in ClusterMetrics
page
> - Update queue/partition related metrics w.r.t per-partition am-resource-percentage
