-------------------------------------------
BTW, what is the reason not to simply use DFSInputStream?
> Erasure Coding: local and remote block reader for coding work in DataNode

> Key: HDFS-8014

> Project: Hadoop HDFS
> Issue Type: Sub-task
> Reporter: Kai Zheng

> 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.
