Change subject: IMPALA-8781: Result spooling tests to cover edge cases and 
cancellation

Just a few nits about the test dimensions after I saw your last comment. 
Specifying the database manually to match the test dimension seems fine. I 
forget the details, but I think it may only automatically switch databases to 
match the workload and dimension when running .test fiels.

http://gerrit.cloudera.org:8080/#/c/13907/10/tests/query_test/test_result_spooling.py
File tests/query_test/test_result_spooling.py:

http://gerrit.cloudera.org:8080/#/c/13907/10/tests/query_test/test_result_spooling.py@26
PS10, Line 26: tpch
tpch_parquet?


http://gerrit.cloudera.org:8080/#/c/13907/10/tests/query_test/test_result_spooling.py@39
PS10, Line 39:           v.get_value('table_format').file_format == 'parquet')
Do we want to run it for all file formats in exhaustive? I think it makes sense 
just to run it on parquet.


http://gerrit.cloudera.org:8080/#/c/13907/10/tests/query_test/test_result_spooling.py@46
PS10, Line 46:     self.run_test_case('QueryTest/result-spooling', vector)
Most or all of the queries explicitly specify "functional", which is text, 
which doesn't line up with the test dimensions. This is kinda confusing. I'd 
suggest either using functional_parquet or just leaving the database off (that 
should work in the .test files, at least).


http://gerrit.cloudera.org:8080/#/c/13907/10/tests/query_test/test_result_spooling.py@58
PS10, Line 58:     result = self.execute_query(query, exec_options)
Maybe make a copy of exec_options, it's a little surprising that this function 
modifies its argument.


http://gerrit.cloudera.org:8080/#/c/13907/10/tests/query_test/test_result_spooling.py@96
PS10, Line 96:         v.get_value('table_format').file_format == 'parquet' and
The same nit applies here that you've specified parquet but are querying text 
tables.
