org.apache.hadoop.hdfs.server.datanode.ReplicaWaitingToBeRecovered
This class represents a replica that is waiting to be recovered. After a datanode restart, any replica in "rbw" directory is loaded as a replica waiting to be recovered. A replica waiting to be recovered does not provision read nor participates in any pipeline recovery. It will become outdated if its client continues to write or be recovered as a result of lease recovery.

        }
        // Restart meta doesn't exist or expired.
        if (loadRwr) {
          newReplica = new ReplicaWaitingToBeRecovered(blockId,
              validateIntegrityAndSetLength(blockFile, genStamp), 
              genStamp, volume, blockFile.getParentFile());
        }
