----------------------------------
Summary: Capacity scheduler: enhance leaf-queue-template capacity
/ maximum-capacity setting
Key: YARN-9893
URL: https://issues.apache.org/jira/browse/YARN-9893
Project: Hadoop YARN
Issue Type: Sub-task
Components: capacity scheduler
Reporter: Peter Bacsko
Capacity Scheduler does not support two percentage values for leaf queue
capacity and maximum-capacity settings. So, you can't do something like this:
{{yarn.scheduler.capacity.root.users.john.leaf-queue-template.capacity=memory-mb=50.0%,
vcores=50.0%}}
On top of that, it's not even possible to define absolute resources:
{{yarn.scheduler.capacity.root.users.john.leaf-queue-template.capacity=memory-mb=16384,
vcores=8}}
Only a single percentage value is accepted.
This makes it nearly impossible to properly convert a similar setting from Fair
Scheduler, where such a configuration is valid and accepted
({{<maxChildResources>}}).
