Subject [jira] [Commented] (HDFS-8156) Add/implement necessary APIs even we just have the system default schema
Date Fri, 17 Apr 2015 23:15:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8156?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14500882#comment-14500882
] 

Kai Zheng commented on HDFS-8156:
---------------------------------

Thanks [~szetszwo] for the good review.
bq.Should chunkSize be renamed to "cellSize"?
In my understanding, "chunk" could be used in erasure coding context, as we would perform
coding chunk by chunk for blocks. "cell" is more used in stripping context. ECSchema is defined
as part of the erasure codec framework so chunkSize is used. It's consistent in the framework
with other parts.
Other points are all good and I will address them next week. Thanks.

> According to the discussion here, this issue was repurposed and modified.
> This is to add and implement some necessary APIs even we just have the system default
schema, to resolve some TODOs left for HDFS-7859 and HDFS-7866 as they're still subject to
further discussion.
