> 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%}}
> 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>}}).
> Note: using absolute resources ({{yarn.scheduler.capacity.root.users.john.leaf-queue-template.capacity=memory-mb=16384,
vcores=8}}) is addressed in YARN-10154.
