> *Investigate how resource allocation configuration could be more consistent
> in CapacityScheduler*
> It would be nice if everywhere where a capacity can be defined could be
> defined the same way:
> * With fixed amounts (e.g. 1 GB memory, 8 vcores, 3 GPU)
> * With percentages
> ** Percentage of all resources (eg 10% of all memory, vcore, GPU)
> ** Percentage per resource type (eg 10% memory, 25% vcore, 50% GPU)
> * Allow mixing different modes under one hierarchy but not under the same
> parent queues.
> We need to determine all configuration options where capacities can be
> defined, and see if it is possible to extend the configuration, or if it
> makes sense in that case.
