             Summary: 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


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 migration. For this 
purpose, we should disallow the REPLACE COLUMNS and CHANGE COLUMN commands for 
these migrated Iceberg tables. ADD COLUMNS are still permitted.
