This > can in turn have an impact in job execution times and cluster utilization. > To this end, we introduce corrective mechanisms that may remove (whenever > needed) container requests from overloaded queues, adding them to less-loaded > ones. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
