Marton Bod commented on HIVE-25643: ----------------------------------- Pushed to master. Thanks [~szita] for the review! > Disable replace cols and change col commands for migrated Iceberg tables > ------------------------------------------------------------------------ > > Key: HIVE-25643 > URL: https://issues.apache.org/jira/browse/HIVE-25643 > Project: Hive > Issue Type: Improvement > Reporter: Marton Bod > Assignee: Marton Bod > Priority: Major > Labels: pull-request-available > Time Spent: 10m > Remaining Estimate: 0h > > Since the Iceberg table migration will intentionally not rewrite the data > files, the migrated table will end up with data files that do not contain the > Iceberg field IDs necessary for safe, reliable schema evolution. For this > purpose, we should disallow the REPLACE COLUMNS and CHANGE COLUMN commands > for these migrated Iceberg tables. ADD COLUMNS are still permitted. -- This message was sent by Atlassian Jira (v8.3.4#803005)
