YARN's capacity scheduler is designed to allow sharing of large cluster across many organizations. The cluster utilization takes into account the capacity guarantees, fairness and SLA's of the organizations for optimization. It provides a stringent set of limits to ensure that single application or user cannot consume disproportionate amount of resources in the cluster.

SLA's basically the timeline before which the job of a particular organization should be completed.
