Wangda Tan updated YARN-4433:
-----------------------------
    Summary: Minimum and increment capacity support should be supported by 
AbstractYarnScheduler  (was: Minimum and increment capacity support should be 
moved to AbstractYarnScheduler)

> Currently, only FairScheduler supports increment capacity different from 
> minimum capacity, it will be useful if we can support this feature in other 
> schedulers.
> Default behavior of minimum/increment resources:
> - Minimum-allocation should > 0
> - Minimum-allocation should be multiple times of increment (to avoid resource 
> fragmentation).
> Different scheduler implementation can overwrite this behavior.
> With this we can have a more fine-grained granularity of resources 
> allocation. (In existing CapacityScheduler without this feature, if 
> minimum-allocation set to 5G, you can only get 5G, 10G, .... With this 
> feature, if you have minimum-allocation set to 5G, and increment-allocation 
> set to 1G, you can ask 5G, 6G, 7G...)
