Gaurav Menghani commented on HBASE-9631:
----------------------------------------
[~apurtell] I don't think that was an *increase*. That seems to be the
probability of the BloomFilter being correct when it returns true. The false
positive rate should be (1 - 0.99...). I would be surprised if the Bloom Filter
is wrong with a probability of 0.99.. or more. Please correct me if I am wrong.

> 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.
