henrib opened a new pull request, #6936:
URL: https://github.com/apache/hive/pull/6936
### What changes were proposed in this pull request?
- New setting `metastore.iceberg.catalog.client-supplied-owner.enabled`
(default `false`).
When disabled, the REST catalog records the authenticated caller as owner
of new
tables and views. Embedded `HiveCatalog` keeps its current behaviour
(`iceberg.hive.client-supplied-owner.enabled`, default `true`).
- `hive.metastore.table.owner`, `Authorized` and
`hive.metastore.view.authorized` are
treated as HMS-managed view properties: they are not copied into HMS
parameters, and
the REST catalog drops them from view create/update requests.
- REST view responses report the owner and `Authorized` state recorded in
HMS for the
returned metadata version.
- `HiveRESTCatalogClient` maps `hive.metastore.view.authorized` back to the
`Authorized`
view parameter; `MetastoreUtil` keeps the HMS-recorded owner when
converting a view.
### Why are the changes needed?
Keeps owner and view authorization state consistent with what HMS records.
See HIVE-29992.
### Does this PR introduce _any_ user-facing change?
Yes. With the default configuration, the Iceberg REST catalog sets the owner
of new
tables and views to the authenticated caller instead of a client-provided
value. The
previous behaviour can be restored with
`metastore.iceberg.catalog.client-supplied-owner.enabled=true`.
### How was this patch tested?
New and updated unit tests: `TestRESTViewDeferredAuthorization`,
`TestIcebergAuthorizer`,
`TestIcebergViewSupport`, `TestHiveHadoopUtil`; new itest
`TestHiveRESTCatalogClientViewAuthorization`.
