> Key: HIVE-28277
> URL: https://issues.apache.org/jira/browse/HIVE-28277
> Project: Hive
> Issue Type: Bug
> Components: Iceberg integration
> Affects Versions: 4.0.0
> Environment: ICEBERG:1.5.2
> HIVE 4.0.0
> Reporter: yongzhi.shao
> Priority: Major
>
> Currently, when I update the location_based_table using hive, hive
> incorrectly empties all data directories and metadata directories.
> After the update statement is executed, the iceberg table is corrupted.

> {code:java}
> --spark 3.4.1 + iceberg 1.5.2:
