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)
