Overview

the 64-bit version of MurmurHash2, supposedly. I have doubts about either this java implementation or the digest-murmurhash gem’s implementation. I don’t get equivalent results when passing in a String into them so I’m wondering which one is most similar to the original C++ implementation.

Either way, for JD Power’s purposes, we just need this java version to be thinly wrapped in ruby b/c it’s the version we’re already using and we need all of our keys to stay the same for now. Therefore, I have no need to figure out which version (this one or digest-murmurhash’s) is more correct.
