Marton Bod created HIVE-25849: --------------------------------- Summary: Disable insert overwrite for bucket partitioned Iceberg tables Key: HIVE-25849 URL: https://issues.apache.org/jira/browse/HIVE-25849 Project: Hive Issue Type: Improvement Reporter: Marton Bod Assignee: Marton Bod
Insert overwrite should be disabled where the target Iceberg table is a bucket partitioned table, since which existing partitions will be overwritten is very hard to predict from a user's POV, as it depends on the bucket hash values calculated for the new dataset's rows. It's better to be on the safe side and disable this operation to avoid unwanted data loss. -- This message was sent by Atlassian Jira (v8.20.1#820001)
