Greg Mann commented on MESOS-3064:
----------------------------------
Good point, [~jieyu]. I think that {{Resource.DiskInfo.Persistence}} would be a
good place for it.
What do you think about the issue of whether this new {{principal}} field
should be required or optional? Making it required would be a breaking change
for frameworks which already use persistent volumes. However, the existing
precedent in the {{ReservationInfo}} and {{RateLimits}} messages is for
{{principal}} to be required, and it seems perhaps wise to require it also for
persistent volume creation. If we do make it a required field, should we do
something like a deprecation cycle during which it's optional?
