Benjamin Mahler commented on MESOS-1592:
----------------------------------------
Yes, this is the piece of "node draining" that allows schedulers to be notified
ahead of time, which allows them to take action proactively. However, the
concept of an inverse offer is not specific to node draining and can be used
for other means as well.
> Introduce the notion of an inverse resource offer.

> Issue Type: Task
> Components: allocation
> Reporter: Benjamin Mahler
>
> 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.
