> *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.
