Subject [jira] [Commented] (YARN-9681) AM resource limit is incorrect for queue
Date Wed, 17 Jul 2019 14:18:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-9681?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16887085#comment-16887085

ANANDA G B commented on YARN-9681:

Hi Sunil

When we submit a app to queue1 in pool1 (Please check the attached screenshots for nodelabels
configuration), the LeafQueue.assignContainers function will update cachedResourceLimitsForHeadroom
to nodelabel pool1's resource 8196.

Then LeafQueue.activateApplications function calculate the 'Maximum Application Master Resources'
of DEFAULT_PARTITION using cachedResourceLimitsForHeadroom. This is wrong actually.

So, each nodelabel should have its own cachedResourceLimitsForHeadroom. So it can be a ConcurrentHashMap
where key is nodelabel and value is ResourceLimits.
