> Key: HIVE-22639
> URL: https://issues.apache.org/jira/browse/HIVE-22639
> Project: Hive
> Issue Type: Bug
> Components: Hive
> Affects Versions: 3.0.0, 3.1.0
> Reporter: Aron Hamvas
> Assignee: Aron Hamvas
> Priority: Major
> Attachments: HIVE-22639.1.patch, HIVE-22639.2.patch, HIVE-22639.patch

> While debugging
> {{TestCrudCompactorOnTez#testCompactionWithSchemaEvolutionAndBuckets()}}, it
> has come to my attention, that even though before compaction, the file name
> of the single bucket in the delta directories is {{bucket_00001}}, in the new
> base, the name of the new single bucket file is {{bucket_00000}}. At the same
> time, the bucket value in the ROW__ID of the records remain the same and
> suggest that the bucket id is 1.
> So the bucket id and the file name do not match. This could lead to problems.
> The test itself does not reveal this issue, although I think that the tests
> should check this, too. At the same time, the tests assume the exact bucket
> id value in cases where it cannot be predicted and fail, even though the
> bucket it does not change after the compaction, so the check should really
> pass.
