> Issue Type: Bug
> Affects Versions: Impala 3.3.0
> Reporter: Anurag Mantripragada
> Assignee: Fang-Yu Rao
> Priority: Critical
> Labels: broken-build

> Another flaky test uncovered due to IMPALA-7608. The test relies on exact cardinality numbers but after IMPALA-7608, these could be indeterministic.
