Kai Sasaki commented on HDFS-8062:

Thank you so much. I updated below points.

* PBHelper
* INodeFile
* BlockInfoStriped
* FSDirectory
* FSNamesystem
* And correspond test classes

I think there are the tasks in ProtocolBuffer layer which are should be done by other JIRA
such as [HDFS-7866|https://issues.apache.org/jira/browse/HDFS-7866].
All ECSchemas used in PBHelper and ProtocolBuffer layer are default one. They should be passed
according the format defined in ProtocolBuffer. We can do this task with [HDFS-7866|https://issues.apache.org/jira/browse/HDFS-7866]
or related ones.
