             Summary: Erasure Coding: local and remote block reader for coding work in DataNode
                 Key: HDFS-8014
                 URL: https://issues.apache.org/jira/browse/HDFS-8014
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Kai Zheng
            Assignee: Zhe Zhang


As a task of HDFS-7344 ECWorker, in either stripping or non-stripping erasure coding, to perform
encoding or decoding, we need first to be able to read locally or remotely data blocks. This
is to come up block reader 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.
