> ChecksumFileSystem does not override the following method
> {code}
> public FSDataOutputStream create(Path f, FsPermission permission,
>       boolean overwrite, int bufferSize, short replication, long blockSize,
>       Progressable progress) throws IOException 
> {code}
> As a consequence, when creating a file with LocalFileSystem and the create method above,
no checksum will be created.
