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

             Summary: Erasure Coding: handle read/write failure for non-stripping coding blocks
                 Key: HDFS-8022
                 URL: https://issues.apache.org/jira/browse/HDFS-8022
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Kai Zheng
            Assignee: Tsz Wo Nicholas Sze


In *non-stripping* case, for (6, 3)-Reed-Solomon, ECWorker reads 6 data blocks and writes
3 parity blocks. We need to handle datanode or network failures when reading or writing local
or remote blocks.
