------------------------------------
Assignee: Attila Jeges
> Update test_hms_integration.py test_compute_stats_get_to_hive to account for
> separate Hive/Impala statistics
> ------------------------------------------------------------------------------------------------------------
>
> Key: IMPALA-9094
> URL: https://issues.apache.org/jira/browse/IMPALA-9094
> Project: IMPALA
> Issue Type: Bug
> Components: Frontend
> Affects Versions: Impala 3.4.0
> Reporter: Joe McDonnell
> Assignee: Attila Jeges
> Priority: Blocker
>
> With newer Hive versions, Impala and Hive stats are kept separately and won't
> overwrite each other. test_hms_integration.py test_compute_stats_get_to_hive
> expects that Hive stats change when Impala does compute stats.
> test_compute_stats_get_to_impala expects that Impala stats change when Hive
> does compute stats. These tests need to be revised. Here are the example test
> failures:
> {noformat}
> metadata/test_hms_integration.py:486: in test_compute_stats_get_to_hive
> assert hive_stats != self.hive_column_stats(table_name, 'x')
> E assert {'# col_name': 'data_type', 'col_name': 'data_type', 'x': 'int'}
> != {'# col_name': 'data_type', 'col_name': 'data_type', 'x': 'int'}
> E + where {'# col_name': 'data_type', 'col_name': 'data_type', 'x':
> 'int'} = <bound method TestHmsIntegration.hive_column_stats of
> <test_hms_integration.TestHmsIntegration object at
> 0xe260e50>>('zbberubbydyldirc.fkqzvzekyqsjnflk', 'x')
> E + where <bound method TestHmsIntegration.hive_column_stats of
> <test_hms_integration.TestHmsIntegration object at 0xe260e50>> =
> <test_hms_integration.TestHmsIntegration object at
> 0xe260e50>.hive_column_stats{noformat}
> If my theory is right, we should flip the test to make sure that Impala
> compute stats doesn't impact Hive and vice versa.
