Daniel Templeton updated YARN-6863: ----------------------------------- Description: In {{FSPreemptionThread.identifyContainersToPreemptOnNode()}}, we add every container we encounter to the preemption list until we meet the desired target. As we head into resource types, that behavior will become more of a problem, but it's technically an issue already because the fair scheduler supports requests with 0 vcores or 0 memory. (was: In {{FSPreemptionThread.identifyContainersToPreempt()}}, we add every container we encounter to the preemption list until we meet the desired target. As we head into resource types, that behavior will become more of a problem, but it's technically an issue already because the fair scheduler supports requests with 0 vcores or 0 memory.) > Fair Scheduler preemption thread should check that a container has the needed > resources before adding it to the preemption list > ------------------------------------------------------------------------------------------------------------------------------- > > Key: YARN-6863 > URL: https://issues.apache.org/jira/browse/YARN-6863 > Project: Hadoop YARN > Issue Type: Bug > Components: fairscheduler > Affects Versions: 3.0.0-alpha4 > Reporter: Daniel Templeton > Priority: Minor > > In {{FSPreemptionThread.identifyContainersToPreemptOnNode()}}, we add every > container we encounter to the preemption list until we meet the desired > target.
