             Summary: Support Resource oversubscription in YARN scheduler
                 Key: YARN-4407
                 URL: https://issues.apache.org/jira/browse/YARN-4407
             Project: Hadoop YARN
          Issue Type: New Feature

Many long running services do not fully use their allocated resources all the time. We could takes advantage of temporarily unused resources to execute low priority jobs such as background analytics, etc. This will definitely improve the resource utilization.
