[jira] [Issue Comment Deleted] (YARN-6378) Negative usedResources
memory in CapacityScheduler
[ https://issues.apache.org/jira/browse/YARN-6378?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

(was: From what I can tell, there's an app : {{application_1487222361993_12379}} which was moved first from interactive to the production queue, and then from production queue to the etl queue . This was a massive application so I'm not sure if the discrepancy in accounting is an artifact of the application being moved twice of it being a massive app and some race condition being triggered. Or if this application's shenanigans were at all involved ;-))
