> 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.
