[jira] [Created] (HBASE-9631) add murmur3 hash

Liang Xie created HBASE-9631:
--------------------------------

             Summary: add murmur3 hash
                 Key: HBASE-9631
                 URL: https://issues.apache.org/jira/browse/HBASE-9631
             Project: HBase
          Issue Type: New Feature
          Components: util
    Affects Versions: 0.98.0
            Reporter: Liang Xie
            Assignee: Liang Xie
         Attachments: 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.
