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.
