> LowCost: A Cost-Based Placement Agent for YARN Reservations
> -----------------------------------------------------------
>
> Key: YARN-3656
> URL: https://issues.apache.org/jira/browse/YARN-3656
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: capacityscheduler, resourcemanager
> Affects Versions: 2.6.0
> Reporter: Ishai Menache
> Assignee: Jonathan Yaniv
> Labels: capacity-scheduler, resourcemanager
> Attachments: LowCostRayonExternal.pdf, YARN-3656-v1.1.patch,
> YARN-3656-v1.patch, lowcostrayonexternal_v2.pdf
>
>
> YARN-1051 enables SLA support by allowing users to reserve cluster capacity
> ahead of time. YARN-1710 introduced a greedy agent for placing user
> reservations. The greedy agent makes fast placement decisions but at the cost
> of ignoring the cluster committed resources, which might result in blocking
> the cluster resources for certain periods of time, and in turn rejecting some
> arriving jobs.
> We propose LowCost – a new cost-based planning algorithm. LowCost “spreads”
> the demand of the job throughout the allowed time-window according to a
> global, load-based cost function.
