Description

Impala use Iceberg’s org.apache.iceberg.mr.Catalogs class to dynamically load and create catalog objects, such as in:

https://github.com/apache/impala/blob/cf9c443ddca7403d2a92b2a01a374749a72e5f8f/fe/src/main/java/org/apache/impala/catalog/iceberg/IcebergCatalogs.java#L104

When a table’s ‘iceberg.catalog’ property points to a catalog defined in hive-site.xml, Impala should not use IcebergHiveCatalog. Instead, it should use Impala’s IcebergCatalogs, which in turn will resolve the correct catalog object through org.apache.iceberg.mr.Catalogs.
