@mxm, What would happen under following cases: taskExecutor releases a
registered slot, then taskExecutor reports its latest slotReport to
ResourceManager, ResourceManager should remove the old slot allocation from its
own view and mark the slot free. So I think we should keep the following code
in the old SlotManager `updateSlotStatus`:
_else {
// slot is reported empty
// check whether we also thought this slot is
empty
if (allocationMap.isAllocated(slotId)) {
LOG.info("Slot allocation info
mismatch! SlotID:{}, current:{}, reported:null",
slotId,
allocationMap.getAllocationID(slotId));
// we thought the slot is in use,
correct it
allocationMap.removeAllocation(slotId);
// we have a free slot!
handleFreeSlot(slot);
}
}_
