[jira] [Updated] (YARN-8427) Don't start opportunistic containers
at container scheduler/finish event with over-allocation
[ https://issues.apache.org/jira/browse/YARN-8427?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

-----------------------------
Issue Type: Sub-task (was: Improvement)
Parent: YARN-1011

> ---------------------------------------------------------------------------------------------
>
> Key: YARN-8427
> URL: https://issues.apache.org/jira/browse/YARN-8427
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: nodemanager
> Reporter: Haibo Chen
> Assignee: Haibo Chen
> Priority: Major
>
> As discussed in YARN-8250, we can stop opportunistic containers from being launched at container scheduler/finish events if the node is already over-allocating itself. This can mitigate the issue that too many opportunistic containers can be launched and then quickly killed.
