Wei Yan reassigned YARN-1010: ----------------------------- Assignee: Wei Yan (was: Alejandro Abdelnur) > FairScheduler: decouple container scheduling from nodemanager heartbeats > ------------------------------------------------------------------------ > > Key: YARN-1010 > URL: https://issues.apache.org/jira/browse/YARN-1010 > Project: Hadoop YARN > Issue Type: Improvement > Components: scheduler > Affects Versions: 2.1.0-beta > Reporter: Alejandro Abdelnur > Assignee: Wei Yan > Priority: Critical > > Currently scheduling for a node is done when a node heartbeats. > For large cluster where the heartbeat interval is set to several seconds this > delays scheduling of incoming allocations significantly. > We could have a continuous loop scanning all nodes and doing scheduling. If > there is availability AMs will get the allocation in the next heartbeat after > the one that placed the request. -- This message is automatically generated by JIRA.
