Kai Sasaki commented on HDFS-8020:
----------------------------------

[~zhz] I agree with you. I also found Erasure coding command was already implemented. So we
can close this.

> As a task of HDFS-7348, to process *stripping* coding commands from NameNode or other
scheduler services/tools, we need to first be able to restore BlockGroup and schema information
in DataNode, which will be used to construct and perform coding work using {{ErasureCoder}}
API.
