    Description

      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.
