Looks good in general, just a few comments.

File tests/common/test_result_verifier.py:

PS3, Line 539:   if verifier and verifier.upper() == 'VERIFY_IS_EQUAL':
             :     order_matters = True
             :   if verifier and verifier.upper() == 'VERIFY_IS_EQUAL_SORTED':
             :     order_matters = False
Can you add tests that use these?

PS3, Line 88: unique_database
The database created here is not used - could use unique_name fixture.


http://gerrit.cloudera.org:8080/#/c/24544/3/tests/custom_cluster/test_trino_interop.py@113
PS3, Line 113:       # Impala only learns about out-of-band HMS objects after 
an INVALIDATE.
             :       self.execute_query("INVALIDATE METADATA")
HMS events still work, right? So Impala sees the database after bit of time.
