Marton Bod reassigned HIVE-25643:
---------------------------------
> 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
>
> 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.
