Anurag Mantripragada updated IMPALA-8730:
-----------------------------------------
Description:
Could be a data loading issue, cardinality estimates are off.
Below is the error message:
{code:java}
metadata/test_explain.py:113: in test_explain_validate_cardinality_estimates
check_cardinality(result.data, '7.30K') metadata/test_explain.py:98: in
check_cardinality query_result, expected_cardinality=expected_cardinality)
metadata/test_explain.py:86: in check_row_size_and_cardinality assert
m.groups()[1] == expected_cardinality E assert '7.00K' == '7.30K' E -
7.00K E ? ^ E + 7.30K E ? ^{code}
was:
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:

check_cardinality(result.data, '7.30K') metadata/test_explain.py:98: in
