> The idea is that for getProtocolVersion, NameNode checks if the client and
> server versions are compatible if the server version is greater than the
> client version. If no, throws a VersionIncompatible exception; otherwise,
> returns the server version.
> On the dfs client side, when creating a NameNode proxy, catches the
> VersionMismatch exception and then checks if the client version and the
> server version are compatible if the client version is greater than the
> server version. If not compatible, throws exception VersionIncomptible;
> otherwise, records the server version and continues.
