Charles Lamb updated HDFS-6375:
-------------------------------
Attachment: HDFS-6375.9.patch
Thanks for the comments Andrew. The .9 patch fixes the indentation issue (I
don't know how that one snuck by me) and adds the two paranoia tests.
I'm not sure how to do the DFSClient Map.keySet -> List trick in JSonUtil since
what we have is an array of Map's, where each Map maps strings to strings. For
each Map we lookup the "name" attribute and that yields the xattr name. If it
were a single Map, then I think we could do the same thing, but it's multiple
maps. But maybe I'm misunderstanding what you're suggesting.

> From the attr(5) manpage:
> {noformat}
> Users with search access to a file or directory may retrieve a list of
> attribute names defined for that file or directory.
> {noformat}
> This is like doing {{getfattr}} without the {{-d}} flag, which we currently
> don't support.
