Arun Suresh reassigned YARN-2888: --------------------------------- Assignee: Arun Suresh > Corrective mechanisms for rebalancing NM container queues > --------------------------------------------------------- > > Key: YARN-2888 > URL: https://issues.apache.org/jira/browse/YARN-2888 > Project: Hadoop YARN > Issue Type: Sub-task > Components: nodemanager, resourcemanager > Reporter: Konstantinos Karanasos > Assignee: Arun Suresh > > Bad queuing decisions by the LocalRMs (e.g., due to the distributed nature of > the scheduling decisions or due to having a stale image of the system) may > lead to an imbalance in the waiting times of the NM container queues. 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)
