> Key: YARN-5165
> URL: https://issues.apache.org/jira/browse/YARN-5165
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: capacityscheduler, fairscheduler, resourcemanager
> Reporter: Carlo Curino
> Assignee: Carlo Curino
> Fix For: 2.8.0

> As a consequence small time granularities (e.g., 1 sec) and long time horizon for a reservation (e.g., months) run rather slow (10 sec).
> Proposed resolution is to switch to interval math in checking, similar to how YARN-4359 does for agents.
