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.
