> h3. Problem
> CREATE TABLE in a REST catalog database fails at catalog-op-executor.cc:111-113 in
> standalone mode and goes to catalogd in hybrid mode. Even with a transport, the
> catalogd path is HMS-bound:
>  * (a) Location: CatalogOpExecutor.java:4322-4324 uses
> MetastoreShim.getPathForNewTable(hiveDatabase, msTbl), but IcebergMetaProvider.loadDb
> (:154-159) returns a Database with only the name set (no location, no parameters).
>  * (b) Existence check: :4303-4306 uses hiveClient.tableExists.
>  * (c) Analysis: CreateTableStmt.java:775-807 throws "Unknown Iceberg catalog type: %s"
> for anything outside the 4 TIcebergCatalog values; :670-674 silently defaults a missing
> 'iceberg.catalog' to HIVE_CATALOG.
>  * (d) Owner: IcebergCatalogOpExecutor.createTable (:105, :113-116) injects
> HiveCatalog.HMS_TABLE_OWNER.
>  * (e) HMS-only steps: populateExternalTableCols (:126-134, called at
> CatalogOpExecutor.java:4361) and addCatalogVersionToTxn (:781-789).
