IMPALA-13747: Use fresh HS2 client for unique_database fixture
Just like IMPALA-13634 bug, unique_database fixture may taint
ImpalaTestSuite.client by setting 'sync_ddl=True' option and never
cleaning it up for test method usage.
This patch fixes unique_database fixture by always creating fresh HS2
client during CREATE DATABASE and DROP DATABASE.
Testing:
- Caught an assert error at test_set_fallback_db_for_functions
Expected: "default.fn() unknown for database default"
Actual: "functional.fn() unknown for database functional"
In this case, shared ImpalaTestSuite.client may have changed database
via ImpalaTestSuite.run_test_case() or
ImpalaTestSuite.execute_wrapper() in other test method.
Removing unused 'vector' argument somehow fixed the issue.
- For both query_test/test_udfs.py and metadata/test_ddl.py:
- Fixed flake8 issues and remove unused pytest fixture.
- Run and pass the tests in exhaustive exploration.
