Ashwin Shankar created YARN-2394: ------------------------------------ Summary: 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: Improvement Components: fairscheduler Reporter: Ashwin Shankar
Preemption based on fair share starvation happens when usage of a queue is less than 50% of its fair share. This 50% is hardcoded. We'd like to make this configurable on a per queue basis, so that we can choose the threshold at which we want to preempt. Calling this config "fairSharePreemptionThreshold". -- This message was sent by Atlassian JIRA (v6.2#6252)
