Subject [jira] [Commented] (HDFS-8882) Use datablocks, parityblocks and cell size from ec zone
Date Mon, 10 Aug 2015 06:38:46 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8882?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14679651#comment-14679651

Walter Su commented on HDFS-8882:
---------------------------------

You have finished HDFS-8558. After HDFS-8854, I'm thinking to pass ECPolicy instead of dataBlkNum+cellSize
to Dispatcher.
For DataStreamer part, You can just replace ECSchema to ECPolicy cleanly after HDFS-8854.
I suggest we hold all patches replated to ECSchema until HDFS-8854 is done. The patch of HDFS-8854
is big(it's a clean refactor) I don't want to make it more complicated. Thanks.

> As part of earlier development, constants were used for datablocks, parity blocks and
cellsize.
> Now all these are available in ec zone. Use from there and stop using constant values.
