> Key: IMPALA-6335
> URL: https://issues.apache.org/jira/browse/IMPALA-6335
> Project: IMPALA
> Issue Type: Improvement
> Components: Infrastructure
> Affects Versions: Impala 2.10.0
> Reporter: Jinchul Kim

> Priority: Minor
> Labels: newbie

> Regarding the decorator "pytest.mark.execute_serially", I saw all the test
> cases are marked as execute_serially in
> tests/shell/test_shell_interactive.py. I guess a few tests should be run
> exclusively, but the other tests do not require the serial option. What do
> you think about this? I think we should consider to use the decorator when
> adding test cases. Minimized serial run can help to reduce overall test
> running time by parallelism.
> I think the following cases do not require the decorator.
> a. Check consistency from test result
> b. Test query cancellation
> c. Test shell options which are effective on local shell
> > From Tim's comment:
> I think you're right that many of the shell tests don't inherently require to
> be executed serially. Some of them would require work to execute in parallel,
> particularly the ones that inspect files like .impalahistory and tests that
> check the values of global impala daemon metrics.
