---------------------------------
Summary: Limit scope of REPLACE COLUMNS for Iceberg tables
Key: HIVE-25328
URL: https://issues.apache.org/jira/browse/HIVE-25328
Project: Hive
Issue Type: Improvement
Reporter: Marton Bod
Assignee: Marton Bod
Replace columns is a rather wildcard operation which can do heavy-weight schema
changes. We would only want to allow this operation for dropping columns for
Iceberg tables. For other changes (adding cols, renaming, type promotion etc.),
we should use the CHANGE COLUMN command.
