Klaus Ma commented on MESOS-3826:
---------------------------------

re #1. resourceOffers will included {{unreserved resources}} and {{reserved 
resources for this role}}; the {{unreserved resources}} can be used by any 
framework
re #2. {{ReservationInfo}} is required by dynamic reservation, I do suggest to 
use framework's principal to reserve resources; why do you want to use other 
framework's principal?

> Add an optional unique identifier for resource reservations

> Thanks to the resource reservation primitives, frameworks can reserve 
> resources. These reservations are per role, which means multiple frameworks 
> can share reservations. This can get very hairy, as multiple reservations can 
> occur on each agent. 
> It would be nice to be able to optionally, uniquely identify reservations by 
> ID, much like persistent volumes are today. This could be done by adding a 
> new protobuf field, such as Resource.ReservationInfo.id, that if set upon 
> reservation time, would come back when the reservation is advertised.
