> 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: Critical
> 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.
