[jira] [Updated] (YARN-2394) Fair Scheduler : ability to configure fairSharePreemptionThreshold per queue
[ https://issues.apache.org/jira/browse/YARN-2394?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Wei Yan updated YARN-2394: -- Attachment: YARN-2394-2.patch Update a patch following the same way as YARN-2395. Each queue inherits fairSharePreemptionThreshold from its parent queue if it doesn't configure in the allocation file. Will rebase the patch once YARN-2395 is in. > Fair Scheduler : ability to configure fairSharePreemptionThreshold per queue > > > Key: YARN-2394 > URL: https://issues.apache.org/jira/browse/YARN-2394 > Project: Hadoop YARN > Issue Type: New Feature > Components: fairscheduler >Reporter: Ashwin Shankar >Assignee: Wei Yan > Attachments: YARN-2394-1.patch, YARN-2394-2.patch > > > Preemption based on fair share starvation happens when usage of a queue is > less than 50% of its fair share.
