> Doesn't support writes because fuse protocol first creates the file then closes it and
re-opens it to start writing to it. So, (until hadoop-1700), we need a work around.
> One way to do this is to open the file with overwrite flag on the second open. For security,
would only want to do this for zero length files (could even check the creation ts too, but
because of clock skew, that may be harder).

> ps since mostly already implemented, this should be a very quick patch
