             Summary: Provide consistent information about partitioned Iceberg tables
                 Key: IMPALA-11538
                 URL: https://issues.apache.org/jira/browse/IMPALA-11538
             Project: IMPALA
          Issue Type: Bug
          Components: Frontend
            Reporter: Zoltán Borók-Nagy


In HMS we don’t store information about Iceberg partitions, we let Iceberg handle them.

In Impala CatalogD/FE/BE we usually treat Iceberg tables as non-partitioned tables, and only care about Iceberg partitions when really needed, e.g. INSERTs need to be partition-aware, DPP for identity-partitioned tables, also SHOW PARTITIONS must show information about the actual Iceberg partitions, etc.

But in some cases the users see inconsistent information because the non-partitioned nature is revealed in some cases. We need to work on this to not confuse users.

Some places that shows partitioned Iceberg tables as non-partiotioned:
* EXPLAIN statements
* SHOW TABLE STATS
