Subject [jira] [Commented] (HDFS-8494) Remove hard-coded chunk size in favor of ECZone
Date Fri, 29 May 2015 04:35:17 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8494?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14564182#comment-14564182

Kai Sasaki commented on HDFS-8494:
----------------------------------

Current {{BlockInfoStriped}} does not keep {{ErasureCodingZone}}. On the other hand, {{BlockInfoStriped}}
needs cellSize to calculate consumed space. Is it necessary to pass {{ErasureCodingZone}}
to {{BlockInfoStriped}}? Is this assumption right?

> 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.
