Till Rohrmann commented on FLINK-4357:
--------------------------------------
I think we also need some kind of {{SlotManager}} on the {{TaskManager}} to
manage which slot has been assigned to which {{JobManager}}. Furthermore, the
slots will offer access to the respective {{JobManagers}} for the tasks which
are running in them.
> Implement TaskManager side of slot allocation from ResourceManager

> The {{ResourceManager}} may tell the {{TaskManager}} to give a slot to a
> specific {{JobManager}}.
> The slot allocation messages are fenced via ({{RmLeaderID}}, {{JobID}},
> {{AllocationID}}, {{ResourceID}}).
> The TM will ack the request ({{RmLeaderID}},{{AllocationID}}) to the RM and
> then offer that slot to the JM. If not accepted by JM, the TM notifies the RM
> that the slot is in fact available.
