Eugene Koifman created HIVE-17296: ------------------------------------- Summary: 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
