commit da3d6fc7f7c656b118bb3570cedf7d7c3158bd0b Author: Gabor Kaszab <[email protected]> AuthorDate: Tue Aug 9 16:02:17 2022 +0200 IMPALA-11429: Set table owner after creating an Iceberg table Iceberg tables are created using Apache Iceberg's API. However, currently Iceberg gets the owner of the process running Iceberg for the owner of the newly created tables. In our case it's the user running catalogd and not the user running the CREATE TABLE statement. Until the Iceberg API is enhanced to accept an owner parameter for table creation, as a workaround this patch adds an extra alter table step right after Iceberg table creation. TestIcebergTable.test_drop_incomplete_table test had to be skipped with this implementation because this would run into a known bug where Impala runs into an infinite loop when the table location is being dropped somewhere during the execution of the first command after CREATE TABLE. In this case the ALTER TABLE SET OWNER is going to be the first command, so IMPALA-11509 would be triggered in case we dropped the table location as this test would. Testing: - Manually creating Iceberg tables and checking the owner. - Added one automated test to create Iceberg tables with different users and checking the output of DESCRIBE FORMATTED to verify the owner. - Turned off TestIcebergTable.test_drop_incomplete_table as described above. - Manually tested when ALTER TABLE fails (hacked Impala code) that the table is created properly.
