Recent testing showed that the pytests are not
respecting the log level and format set in
conftest.py's configure_logging(). It is using
the default log level of WARNING and the
default formatter.
The issue is that logging.basicConfig() is only
effective the first time it is called. The code
in lib/python/impala_py_lib/helpers.py does a
call to logging.basicConfig() at the global
level, and conftest.py imports that file. This
renders the call in configure_logging()
ineffective.
To avoid this type of confusion, logging.basicConfig()
should only be called from the main() functions for
libraries. This removes the call in lib/python/impala_py_lib
(as it is not needed for a library without a main function).
It also fixes up various other locations to move the
logging.basicConfig() call to the main() function.
Testing:
- Ran the end to end tests and custom cluster tests
- Confirmed the logging format
- Added an assert in configure_logging() to test that
the INFO log level is applied to the root logger.

Some negative tests produce core dumps intentionally. We should have a
way of removing these as part of test cleanup.
For custom cluster tests, it's likely the cores may actually be generated
during the base class setup phase, which means it's too early for the
test fixture to really be useful. Such was the case with the test case
TestAuthorizationProvider::test_invalid_provider_flag. In this instance,
we had to add the same steps directly to the tests.
Testing done:
For test_invalid_provider_flag, I made sure I had pre-existing core files
in the IMPALA_HOME directory, then ran the test to confirm new cores were
removed.
