    Description

      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.
