> ----------------------------------------------------------

> Key: IMPALA-11710
> URL: https://issues.apache.org/jira/browse/IMPALA-11710
> Project: IMPALA
> Issue Type: Bug
> Reporter: Noemi Pap-Takacs
> Assignee: Zoltán Borók-Nagy
> Priority: Major
> Labels: impala-iceberg
>
> This issue occurs in true external Hive Catalog tables.
> Iceberg stores the default file format in a table property called
> 'write.format.default'. HMS also stores this value loaded from the Iceberg
> metadata json file.
> However, when this table property is altered through Impala, it is only
> changed in HMS, but does not update the Iceberg snapshot. When the table data
> is reloaded from Iceberg metadata, the old value will appear in HMS and the
> change is lost.
> This bug does not affect table properties that are not stored in Iceberg,
> because they will not be reloaded.
