> NN starts a block recovery, which will synchronize block replicas on
> different DNs. In the end one of DNs will report the list of the nodes
> containing the consistent replicas to the NN via commitBlockSynchronization()
> call. The NPE happens if just before processing commitBlockSynchronization()
> NN removes from active one of DNs that are then reported in the call.
