> 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
>  * COMPUTE [INCREMENTAL]STATS
