             Summary: Erasure Coding: local and remote block writer for coding work in DataNode
                 Key: HDFS-8015
                 URL: https://issues.apache.org/jira/browse/HDFS-8015
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Kai Zheng
            Assignee: Li Bo


As a task of HDFS-7344 ECWorker, in either stripping or non-stripping erasure coding, to perform
encoding or decoding, we need to be able to write data blocks locally or remotely. This is
to come up block writer facility in DataNode side. Better to think about the similar work
done in client side, so in future it's possible to unify the both.
