Guangya Liu commented on MESOS-3338: ------------------------------------ After some discussion with [~alex-mesos] , his concern is that if we reserved resources for a role, it's not available any more. But from my understanding, even if the resource is reserved, if this resource is not allocated, we should still consider it as available resource. [~mcypark] Can u please show some comments here?
