Subject [jira] [Commented] (HDFS-3206) oev: miscellaneous xml cleanups
Date Thu, 05 Apr 2012 19:12:23 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3206?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13247544#comment-13247544
] 

Bikas Saha commented on HDFS-3206:
----------------------------------

At a higher level, is it ok for no user owner to exist and only have a group owner?
The current XML code seems to imply that a user will always be there. If that is true, and
this bug showed up then it implies some namenode code is broken because it allows ownership
to be group only.

Aside from that, the XML serde code should not reflect namenode behavior. So the fix looks
good.

> * SetOwner operations can change both the user and group which a file or directory belongs
to, or just one of those.  Currently, in the XML serialization/deserialization code, we don't
handle the case where just the group is set, not the user.  We should handle this case.
> * consistently serialize generation stamp as GENSTAMP.
