[jira] [Updated] (YARN-6863) Fair Scheduler preemption thread
should check that a container has the needed resources before adding it to
the preemption list
[ https://issues.apache.org/jira/browse/YARN-6863?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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.)
