Hi Jacek,
This applies to all schedulers actually -- it just tells Spark to re-check the
available nodes and possibly launch tasks on them, because a new stage was
submitted. Then when any node is available, the scheduler will call the
TaskSetManager with an "offer" for the node.

Hi,
Whenever I see `backend.reviveOffers()` I'm struggling myself with
properly explaining what it does. My understanding is that it requests
a SchedulerBackend (that's responsible for talking to a cluster
manager) to...that's the moment I'm not sure about.
How would you explain
