> An "inverse" resource offer means that Mesos is requesting resources back from the framework, possibly within some time interval.
> This can be leveraged initially to provide more automated cluster maintenance, by offering schedulers the opportunity to move tasks to compensate for planned maintenance. Operators can set a time limit on how long to wait for schedulers to relocate tasks before the tasks are forcibly terminated.
> Inverse resource offers have many other potential uses, as it opens the opportunity for the allocator to attempt to move tasks in the cluster through the co-operation of the framework, possibly providing better over-subscription, fairness, etc.
