Murmur for files

[jeusdi]

Could you provide any way to calculate a murmur hash code from a long file.

Using traditional MessageDigest in java, we are reading the file incrementally:

while ((bytesCount = fis.read(byteArray)) != -1) {
    digest.update(byteArray, 0, bytesCount);
}

// Get the hash's bytes
byte[] bytes = digest.digest();

Any ideas?
