Zhe Zhang commented on HDFS-8494:
---------------------------------

Based on the above discussion, I think we have agreed to go with approach A at this stage.

I'm also OK with moving this JIRA to HDFS-8031.

> 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.
