------------------------

             Summary: 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


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.
