-------------------------------------
Summary: Migrate to Murmur hash for shuffle and bucketing
Key: HIVE-18910
URL: https://issues.apache.org/jira/browse/HIVE-18910
Project: Hive
Issue Type: Bug
Reporter: Deepak Jaiswal
Assignee: Deepak Jaiswal
Hive uses JAVA hash which is not as good as murmur for better distribution and
efficiency in bucketing a table.
Migrate to murmur hash but still keep backward compatibility for existing users
so that they dont have to reload the existing tables.
