Subject [jira] [Commented] (HADOOP-10561) Copy command with preserve option should handle Xattrs

Charles Lamb commented on HADOOP-10561:
---------------------------------------

Hi Yi,

I thought we had standardized on "XAttr" as opposed to XATTR or xattr. It doesn't matter to
me which one we use, but I do want us to be consistent. In the code we've been using XAttr
as a general rule, modulo any specific camel-casing that needs to be done.

> 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
