-----------------------------------------
> Partition column rename support for Iceberg tables
> --------------------------------------------------
>
> Key: HIVE-25375
> URL: https://issues.apache.org/jira/browse/HIVE-25375
> Project: Hive
> Issue Type: Bug
> Reporter: Ádám Szita
> Assignee: Ádám Szita
> Priority: Major
>
> Currently ALTER TABLE CHANGE COLUMN statement only updates the Iceberg-backed
> table's schema, but not it's partition spec. Updating the spec is required to
> allow subsequent partition spec changes (like set partition spec calls) to
> succeed.
> Note: to do this in HiveIcebergMetaHook class we can't just create an
> updateSchema and an updatePartitionSpec object, do the modifications and
> commit both of them, as the last commit will fail due to invalid base. We
> might want to do this in two separate steps instead.
