org.apache.hadoop.hdfs.server.protocol.BlockRecoveryCommand

BlockRecoveryCommand is an instruction to a data-node to recover the specified blocks. The data-node that receives this command treats itself as a primary data-node in the recover process. Block recovery is identified by a recoveryId, which is also the new generation stamp, which the block will have after the recovery succeeds.
