Michael Park commented on MESOS-2205:
-------------------------------------
Thanks [~nekto0n] so much for reading the doc and providing feedback!
{quote}Can you clarify which HTTP status(es) will be used?{quote}
For authorization issues we'll return {{401 Unauthorized}} as we do everywhere
else, in the case where the request cannot be satisfied by Mesos due to the
current state of the cluster, I think we can return maybe {{403 Forbidden}} as
we do in [r31228](https://reviews.apache.org/r/31228/) for example, or maybe a
{{409 Conflict}}. Do you have a recommendation in mind?
{quote}What happens if framework attempt to reserve/unreserve fails (if it
can)?{quote}
If the framework requests to (un)reserve resources that does not exist in the
offered resources, that's a validation error and the operation will be dropped.
This is symmetric to how invalid {{TaskInfo}}s for launch tasks are dropped.
That will be all that happens for (un)reserve failures in v1. Once we validate
the (un)reserve operation on the master, we know that the (un)reserve operation
will succeed since the resources are currently offered to the framework and
therefore are available to them. Having said that, in the future we'll likely
want to add {{StatusUpdate}}-like messages for reservations in order to report
successful checkpoint completion on the slave.
