#2364

as issue #2364 describe, when increasedDeserved is Is greater than sum of remaining and decreasedDeserved, Sub is panic.

That's because the requested resources plus the guarantee resources are greater than the total cluster resources. In this case, there are no more resources to allocate to the queue's deserved resource

/hold @qiankunli I tried to simulate the bug scenario according to the proportion plugin implementation. I found that the root reason seems to be here. We should rethink the relationship within the queue.attr. Please help take a look at that. Thanks!
