----------------------------------
Priority: Blocker (was: Critical)
> Acid tests with multiple splits
> -------------------------------
>
> Key: HIVE-17296
> URL: https://issues.apache.org/jira/browse/HIVE-17296
> Project: Hive
> Issue Type: Test
> Components: Transactions
> Affects Versions: 3.0.0
> Reporter: Eugene Koifman
> Assignee: Eugene Koifman
> Priority: Blocker
>
> data files in an Acid table are ORC files which may have multiple stripes
> for such files in base/ or delta/ (and original files with non acid to acid
> conversion) are split by OrcInputFormat into multiple (stripe sized) chunks.
> There is additional logic in in OrcRawRecordMerger
> (discoverKeyBounds/discoverOriginalKeyBounds) that is not tested by any E2E
> tests since none of the have enough data to generate multiple stripes in a
> single file.
> testRecordReaderOldBaseAndDelta/testRecordReaderNewBaseAndDelta/testOriginalReaderPair
> in TestOrcRawRecordMerger has some logic to test this but it really needs e2e
> tests.
> With ORC-228 it will be possible to write such tests.
