[ https://issues.apache.org/jira/browse/HBASE-9631?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Andrew Purtell updated HBASE-9631: -- Resolution: Fixed Fix Version/s: 0.98.0 Release Note: This change provides support for MurmurHash3, the successor to MurmurHash2. It is not selected by default but can be used by changing the configuration setting hbase.hash.type to murmur3. For new installs only. You must not make this change to an existing cluster. Hadoop Flags: Reviewed Status: Resolved (was: Patch Available) Committed to trunk. Thanks for the patch [~xieliang007] 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 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. -- This message was sent by Atlassian JIRA (v6.1#6144)
