Subject [jira] [Commented] (HDFS-2006) ability to support storing extended attributes per file
Date Mon, 21 Apr 2014 22:01:16 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2006?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13976102#comment-13976102

Andrew Wang commented on HDFS-2006:
-----------------------------------

I think any committer can make a branch, so I went ahead and did it:

https://svn.apache.org/repos/asf/hadoop/common/branches/HDFS-2006/

Let's commit and review subtasks there, this will hopefully be a quick development and merge
cycle :)

> It would be nice if HDFS provides a feature to store extended attributes for files, similar
to the one described here: http://en.wikipedia.org/wiki/Extended_file_attributes. 
> The challenge is that it has to be done in such a way that a site not using this feature
does not waste precious memory resources in the namenode.
