Subject [jira] [Commented] (HDFS-7348) Erasure Coding: striped block recovery
Date Tue, 28 Apr 2015 22:31:06 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7348?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14518240#comment-14518240

Zhe Zhang commented on HDFS-7348:
---------------------------------

A quick comment first: 

A the DN level I don't think we need to care about {{cellSize}}? Since we always recover entire
blocks, the client-side logic taking care of cells can be simplified here.
