> Key: IMPALA-14782
> URL: https://issues.apache.org/jira/browse/IMPALA-14782
> Project: IMPALA
> Issue Type: Improvement
> Reporter: Zoltán Borók-Nagy
> Assignee: Mihaly Szjatinya
> Priority: Major
> Labels: impala-iceberg
>
> Catalogs [1] is the only reason we depend on iceberg-mr. And the Iceberg
> community wants to deprecate it.
> CatalogUtil [2] has all the functionality we need. Only limitation is that it
> doesn't support HadoopTables, but they are supported natively by Impala
> anyway.
