--------------------------------------
Summary: 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
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
