IMPALA-10166 (part 1): ALTER TABLE for Iceberg tables
This patch mainly implements ALTER TABLE for Iceberg
tables, we currently support these statements:
* ADD COLUMNS
* RENAME TABLE
* SET TBL_PROPERTIES
* SET OWNER
We forbid DROP COLUMN/REPLACE COLUMNS/ALTER COLUMN in this
patch, since these statemens may make Iceberg tables unreadable.
We may support column resolution by field id in the near future,
after that, we will support COLUMN/REPLACE COLUMNS/ALTER COLUMN
for Iceberg tables.
Here something we still need to pay attention:
1.RENAME TABLE is not supported for HadoopCatalog/HadoopTables,
even if we already implement 'RENAME TABLE' statement, so we
only rename the table in the Hive Metastore for external table.
2.We cannot ADD/DROP PARTITION now since there is no API for that
in Iceberg, but related work is already in progess in Iceberg.
Testing:
- Iceberg table alter test in test_iceberg.py
- Iceberg table negative test in test_scanners.py
- Rename tables in iceberg-negative.test
