Zhe Zhang commented on HDFS-8020:
---------------------------------
Actually {{DNA_CODEC}} is sufficient because we can always deduct whether the
command is for encoding or decoding (or both) from
{{BlockECRecoveryInfo#liveBlockIndices}}.
I think work on this JIRA should start after we have {{ECSchema}} class. Then
this JIRA should add the schema to the {{BlockECRecoveryInfo}}
> Erasure Coding: restore BlockGroup and schema info from stripping coding
> command

> As a task of HDFS-7344, to process *stripping* coding commands from NameNode

> BlockGroup and schema information in DataNode, which will be used to
> construct coding work.
