-------------------------------------
Summary: 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: Improvement
Reporter: Szilard Nemeth
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%
