Elliott Clark commented on HBASE-9631:
--------------------------------------
What do we gain by just having that hash there if it's not used? The hash is
interesting, should we turn it on by default ?
> add murmur3 hash

> 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.
