Szilard Nemeth updated YARN-10886:
----------------------------------
Parent Issue: YARN-10888 (was: YARN-10496)
> Cluster based and parent based max capacity in Capacity Scheduler
> -----------------------------------------------------------------
>
> Key: YARN-10886
> URL: https://issues.apache.org/jira/browse/YARN-10886
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Szilard Nemeth
> Priority: Major
>
> We want to introduce the percentage modes relative to the cluster, not the
> parent, i.e
> The property root.users.maximum-capacity will mean one of the following
> things:
> *Either Parent Percentage:* maximum capacity relative to its parent. If it’s
> set to 50, then it means that the capacity is capped with respect to the
> parent. This can be covered by the current format, no change there.
> *Or Cluster Percentage:* maximum capacity expressed as a percentage of the
> overall cluster capacity. This case is the new scenario, for example:
> yarn.scheduler.capacity.root.users.max-capacity = c:50%
> yarn.scheduler.capacity.root.users.max-capacity = c:50%, c:30%
