> Project: IMPALA
> Issue Type: Bug
> Components: Infrastructure
> Affects Versions: Impala 4.0.0
> Reporter: Riza Suminto
> Assignee: Riza Suminto
> Priority: Major
>
> IMPALA-11123 add assertion to verify NumFileMetadataRead in
> parquet-stats-agg.test. We found that in the multiblock test, the number of
> NumFileMetadataRead can differ in erasure coding configuration. This is most
> likely because erasure coded setup create less files. Below is the stack
> trace:
> {code:java}
> query_test/test_aggregation.py:331: in test_parquet_count_star_optimization
> self.run_test_case('QueryTest/parquet-stats-agg', vector, unique_database)
> common/impala_test_suite.py:743: in run_test_case
> update_section=pytest.config.option.update_results)
> common/test_result_verifier.py:653: in verify_runtime_profile
> % (function, field, expected_value, actual_value, op, actual))
> E AssertionError: Aggregation of SUM over NumFileMetadataRead did not match
> expected results.
> E EXPECTED VALUE:
> E 6
> E
> E
> E ACTUAL VALUE:
> E 5
> E
> E OP:
> E :
> E {code}
