[jira] [Resolved] (YARN-10151) Disable Capacity Scheduler's move
app between queue functionality
[ https://issues.apache.org/jira/browse/YARN-10151?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Wangda Tan resolved YARN-10151.
-------------------------------
Resolution: Won't Fix
Thanks folks for commenting about YARN-9838. I think we don't need this change now given we have a fix of the reported issue already.

> Saw this happened in many clusters: Capacity Scheduler cannot work correctly with the move app between queue features. It will cause weird JMX issue, resource accounting issue, etc. In a lot of causes it will cause RM completely hung and available resource became negative, nothing can be allocated after that. We should turn off CapacityScheduler's move app between queue feature. (see: {{org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler#moveApplication}} )
