I also `+1` for the first approach, but I would like to wait for
@tillrohrmann 's opinion.
And I also curious about one thing, that is currently when ResourceManager
allocate a slot for the `pendingSlotRequest`, it send JM's information to the
TM, and let TM offer the slot to the JM. What I wonder is that why the
ResourceManager doesn't send the slot's TM information to the JM, and let the
JM fetch slot from TM, is there some special reasons? This problem seems should
not exists, if RM send slot's TM information to JM and let JM fetch slot from
TM.
