Deepak Jaiswal created HIVE-18910: ------------------------------------- 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
