> HDFS client protocol is not a guarantee of the immutability of files - the 
> synthetic file-id includes the mtime of the file as well, which is a 
> fail-safe for filesystems which implement the client wire protocol without 
> offering the same storage side restrictions on immutability (i.e allow NFS 
> read-write-modify on the backend).
