Fix Version/s: Impala 4.0
Resolution: Fixed
> Use unqualified table references in .test files run from test_queries.py

> Key: IMPALA-6628
> URL: https://issues.apache.org/jira/browse/IMPALA-6628
> Project: IMPALA
> Issue Type: Improvement
> Components: Infrastructure
> Reporter: Alexander Behm
> Assignee: Qifan Chen
> Priority: Major
> Fix For: Impala 4.0
>
>
> To increase our test coverage over different file formats we should go
> through the .test files referenced from test_queries.py and switch to using
> unqualified table references where possible.
> The state today is that in the exhaustive exploration strategy we run every
> .test file once for every file format. However, since many .test use
> fully-qualified table references we are not actually getting coverage over
> all formats, so we are spending the time to run the tests but not getting the
> coverage we'd like.
> I skimmed a few files and identified that at least these could be improved:
> analytic-fns.test
> subquery.test
> limit.test
> top-n.test
> Likely there are more .test files. Probably there are similar issues in
> different .py files as well, but to keep this JIRA focused I propose we focus
> on test_queries.py first.
> *What to do*
> * Go through the .test files and change fully-qualified table references to
> unqualified table references where possible. Our test framework issues a "use
> <database" before running each such test. Different databases have different
> file formats.
> * Example: The fully-qualified table reference "functional.alltypes" should
> be changed to an unqualified table reference "alltypes"
> * Make sure the tests pass in exhaustive
