Kai Zheng commented on HDFS-8494:
---------------------------------
bq. BlockInfoStriped needs cellSize to calculate consumed space.
Did HDFS-8375 miss the change required here? What's the value that's used in
existing codes?
bq. Is it necessary to pass ErasureCodingZone to BlockInfoStriped?
Please don't. If necessary please just pass {{cellSize}} along with schema as
did in HDFS-8375.
[~vinayrpet], do we have anything to add here regarding the chunkSize/cellSize
stuff here?
I thought we could change {{HdfsConstants.BLOCK_STRIPED_CELL_SIZE}} to
{{DEFAULT_BLOCK_STRIPED_CELL_SIZE}} and ensure it's only used when really
necessary.
> Remove hard-coded chunk size in favor of ECZone

> Key: HDFS-8494
> URL: https://issues.apache.org/jira/browse/HDFS-8494
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Affects Versions: HDFS-7285
> Reporter: Kai Sasaki
> Assignee: Kai Sasaki
> Fix For: HDFS-7285
>
>
> 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.
