[jira] [Updated] (YARN-3920) FairScheduler Reserving a node for a container should be configurable to allow it used only for large containers

Today we let this be used even for a small container request. This has a huge impact on scheduling since we block other scheduling requests until that reservation is fulfilled. We should make this configurable so its impact can be minimized by limiting it for large container requests as originally intended. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
