Subject [jira] [Created] (MESOS-7403) Resources::apply(const Offer::Operation&) should fail when a shared persistent volume can't be removed

Yan Xu created MESOS-7403:
-----------------------------

             Summary: Resources::apply(const Offer::Operation&) should fail when a shared
persistent volume can't be removed
                 Key: MESOS-7403
                 URL: https://issues.apache.org/jira/browse/MESOS-7403
             Project: Mesos
          Issue Type: Bug
            Reporter: Yan Xu


The handling of {{Offer::Operation::DESTROY}} in {{Try<Resources> Resources::apply(const
Offer::Operation& operation) const;}} simply does a subtraction of the volumes from the
resources. For regular persistent volumes this should suffice but for shared persistent volumes
if there are multiple copies of the same shared volume in the resources object, the subtraction
can't remove the volume, it simply removes a copy.

This being a {{DESTROY}} operation means we do want to completely remove it and if we can't,
the {{apply}} method should fail.
