--------------------------------------------
Summary: TestExplain.test_explain_validate_cardinality_estimates
flakiness due to reliance on exact cardinality numbers.
Key: IMPALA-8730
URL: https://issues.apache.org/jira/browse/IMPALA-8730
Project: IMPALA
Issue Type: Bug
Affects Versions: Impala 3.3.0
Reporter: Anurag Mantripragada
Assignee: Fang-Yu Rao
Another flaky test uncovered due to IMPALA-7608. The test relies on exact
cardinality numbers but after IMPALA-7608, these could be indeterministic.
Below is the error message:
{code:java}
metadata/test_explain.py:113: in test_explain_validate_cardinality_estimates
