> MurmurHash3 is the successor to MurmurHash2. It comes in 3 variants - a 32-bit version
that targets low latency for hash table use and two 128-bit versions for generating unique
identifiers for large blocks of data, one each for x86 and x64 platforms.
> several open source projects have added murmur3 already, like cassandra, mahout, etc.
> I just port the murmur3 from MAHOUT-862. due to compatibility, let's keep the default
Hash algo(murmur2) without changing.
