Teddy Choi created HIVE-21011: --------------------------------- Summary: Upgrade MurmurHash 2.0 to 3.0 in vectorized map and reduce operators Key: HIVE-21011 URL: https://issues.apache.org/jira/browse/HIVE-21011 Project: Hive Issue Type: Improvement Reporter: Teddy Choi Assignee: Teddy Choi
HIVE-20873 improved map join performance by using MurmurHash 3.0. However, there's more operators that can use it. VectorMapJoinCommonOperator and VectorReduceSinkUniformHashOperator use MurmurHash 2.0, so it can be upgraded to MurmurHash 3.0. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
