             Summary: PIpieline recovery near the end of a block may fail
                 Key: HDFS-9561
                 URL: https://issues.apache.org/jira/browse/HDFS-9561
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Kihwal Lee


When the client wants to add additional nodes to the pipeline during a 
recovery, it will fail if all existing replicas are already finalized.  This is 
because the partial block copy only works when the replica is in rbw.  Clients 
cannot reliably tell whether a node has finalized the replica during a recovery.
