Kai Sasaki commented on HDFS-8494:
----------------------------------
{{BlockInfoStriped#spaceConsumed}} looks need BLOCK_STRIPED_CELL_SIZE here.
Originally, does it need to it in order to calculate consumed space?
{code:java}
public long spaceConsumed() {
// In case striped blocks, total usage by this striped blocks should
// be the total of data blocks and parity blocks because
// `getNumBytes` is the total of actual data block size.
return StripedBlockUtil.spaceConsumedByStripedBlock(getNumBytes(),
this.schema.getNumDataUnits(), this.schema.getNumParityUnits(),
BLOCK_STRIPED_CELL_SIZE);
}
{code}
> 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.
