-----------------------------------------

             Summary: Handle write failure for EC blocks
                 Key: HDFS-7672
                 URL: https://issues.apache.org/jira/browse/HDFS-7672
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: hdfs-client
            Reporter: Tsz Wo Nicholas Sze
            Assignee: Tsz Wo Nicholas Sze


For (6, 3)-Reed-Solomon, a client writes to 6 data blocks and 3 parity blocks concurrently.  We need to handle datanode or network failures when writing a EC BlockGroup.
