Zhe Zhang commented on HDFS-8494:
---------------------------------
We can also consider creating a data structure with both EC schema and
{{cellSize}} to represent _EC policy_ for the file. Something like
{{ErasureCodingZone}}, but minus the {{dir}}. [~vinayrpet] I think we discussed
this under HDFS-8375 and HDFS-8408. What's your take on this?
> 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 {{cellSize}} in addition to {{ECSchema}}
> when its initialization.
