What do you mean by "actual NameNode methods/functions"? I believe there was an effort during the development of AvatarNode to use BookKeeper (http://zookeeper.apache.org/doc/r3.3.3/bookkeeperOverview.html) to distribute the edit log. Is this what you mean?

That effort ran into various problems but I don't know the detail.
