Yi Liu commented on HDFS-8015:
------------------------------
Hi Bo, for the striped block recovery in HDFS-7348, we don't need to a block
writer, it's convenient to send packet directly. I will update an initial patch
in that JIRA later today.
> 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.
