I am not very sure, but a detailed document will really help to know about the use cases which you are trying to address. As Jason told, it looks similar to the overcommit effort happening in YARN-1011/YARN-5215. > Lease/Reclaim Extension to Yarn > ------------------------------- > > Key: YARN-5261 > URL: https://issues.apache.org/jira/browse/YARN-5261 > Project: Hadoop YARN > Issue Type: New Feature > Components: scheduler > Reporter: Yu > Attachments: YARN-5261-1.patch > > > In some clusters outside of Yarn, the machines resources are not fully utilized, e.g., resource usage is quite low at night. > To better utilize the resources while keep the existing SLA of the cluster, Lease/Reclaim Extension to Yarn is introduced. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: yarn-issues-help@hadoop.apache.org
