Description

Fair Scheduler supports mixed mode for shares (FS equivalent of capacity). An example scenario of such configuration:

root.a.capacity [memory-mb=7268, vcores=8]

root.a.a1.capacity 50

root.a.a2.capacity 50

This above scenario is not supported in CS today because despite CS already permits using weight mode and relative/percentage mode in the same hierarchy the absolute mode and relative mode is mutually exclusive.

This improvement is a natural extension of CS to lift this limitation.
