Subject [jira] [Commented] (HDFS-7889) Subclass DFSOutputStream to support writing striping layout files
Date Fri, 10 Apr 2015 07:36:13 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7889?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14489106#comment-14489106

Li Bo commented on HDFS-7889:
-----------------------------

Thanks for the careful review by Kai and Zhe.
Patch 012 fix most of the problems above.
I am not using {{StripingUtil}} because it has not been committed to branch. When it's committed,
{{StripedDataStreamer#unwrapBlockGroup}} can be replaced. I have find a problem in {{BlockManager}},
I will later create a JIRA about it. All the unit tests pass after disable {{else if (storedBlock.getNumBytes()
!= reported.getNumBytes())}} in {{BlockManager}}.
