> 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
> Fix For: 2.3.0
>
> Attachments: YARN-1010.patch, YARN-1010.patch
>
>
> 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.
