-----------------------------------
> Iceberg: Allow IOW on empty table with Partition Evolution
> ----------------------------------------------------------
>
> Key: HIVE-26868
> URL: https://issues.apache.org/jira/browse/HIVE-26868
> Project: Hive
> Issue Type: Improvement
> Reporter: Ayush Saxena
> Assignee: Ayush Saxena
> Priority: Major
>
> In case an iceberg table has gone through partition evolution, we don't allow
> an IOW operation on it.
> But if it is empty, we can allow an IOW since there ain't any data which can
> get messed by overwrite.
> This helps to compact data, & merge the delete files into data file
> via
> Truncate -> IOW with Snapshot ID before Truncate.
> Same flow is used by Impala for compacting Iceberg tables.
