> The CapacityScheduler's minimum-allocation-mb is set to 1024.
> The FIFO's minimum-allocation-mb meanwhile, is 128.
> I propose changing the formers' minimum to that amount as well. 1024 is way too much as a default, wastes "slots" on NMs - and I also do not see why CS has to deviate that settings from the FIFO default.
