Review Comment:
> Actually, this situation can happen at any time, not just between
"registerDataNode" and "blockReport". Why do you think that after the DN is
re-registered, the probability of the above situation happening will increase,
and it needs to be dealt with specifically?
Yes, there are some other situations can cause this case. And I don't think
the probability of the above situation happening will increase.
I just think we have a chance to reduce this case. So I think we need to do
it.
