[jira] [Updated] (YARN-5831) Propagate allowPreemptionFrom flag all
the way down to the app
[ https://issues.apache.org/jira/browse/YARN-5831?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Karthik Kambatla updated YARN-5831:
-----------------------------------
Parent Issue: YARN-5990 (was: YARN-4752)
> Propagate allowPreemptionFrom flag all the way down to the app
> --------------------------------------------------------------
>
> Key: YARN-5831
> URL: https://issues.apache.org/jira/browse/YARN-5831
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: fairscheduler
> Reporter: Karthik Kambatla
>
> FairScheduler allows disallowing preemption from a queue. When checking if preemption for an application is allowed, the new preemption code recurses all the way to the root queue to check this flag.
> Propagating this information all the way to the app will be more efficient.
