Kai Sasaki commented on HDFS-8494:
----------------------------------
[~drankye] Thank you for reviewing. I can update 1. However I have a question
about point 2. Although we can restore cell size from ECZone, is it possible to
restore ECZone when restoring file system from fsimage file? In this case
inside {{FSImageLoader}} we seem to be unable to restore ECZone information
with current code.
> Remove hard-coded chunk size in favor of ECZone

> It is necessary to remove hard-coded values inside NameNode configured in
> {{HdfsConstants}}. In this JIRA, we can remove {{chunkSize}} gracefully in
> favor of HDFS-8375.
> Because {{cellSize}} is now originally stored only in {{ErasureCodingZone}},
> {{BlockInfoStriped}} can receive {{ErasureCodingZone}} instead of
> {{ECSchema}} when its initialization.
