 Key: HBASE-9631

 Project: HBase
  Issue Type: New Feature
  Components: util
Affects Versions: 0.98.0
Reporter: Liang Xie
Assignee: Liang Xie
 Fix For: 0.98.0

 Attachments: HBase-9631-v2.txt, HBase-9631.txt


 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.
