    Attachment: AvatarNode.20.patch

Sorry, the last patch was made agains our internal tree.
This one is modified to be applied agains hadoop-0.20 trunk.

I will be working on creating a patch against trunk, but it will take some time. In the meanwhile
this one seems to compile OK against hadoop-0.20
