Subject [jira] [Commented] (HADOOP-10561) Copy command with preserve option should handle Xattrs
Date Wed, 11 Jun 2014 17:35:05 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10561?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14028074#comment-14028074
] 

Chris Nauroth commented on HADOOP-10561:
----------------------------------------

The patch looks good, but can we also please update the shell documentation?

http://hadoop.apache.org/docs/r2.4.0/hadoop-project-dist/hadoop-common/FileSystemShell.html#cp

Currently, it doesn't mention the preserve option at all.  We can either roll the documentation
change right into this patch, or file a separate issue for later follow-up.

> The design docs for Xattrs stated that we handle preserve options with copy commands
> From doc:
> Preserve option of commands like “cp -p” shell command and “distcp -p” should
work on XAttrs. 
> In the case of source fs supports XAttrs but target fs does not support, XAttrs will
be ignored 
> with warning message
