---------------------------------
Summary: Vectorization acid/inputformat check should allow
NullRowsInputFormat/OneNullRowInputFormat
Key: HIVE-18742
URL: https://issues.apache.org/jira/browse/HIVE-18742
Project: Hive
Issue Type: Bug
Components: Vectorization
Reporter: Jason Dere
Assignee: Jason Dere
Attachments: HIVE-18742.1.patch
Vectorizer.verifyAndSetVectorPartDesc() has a Preconditions check to ensure the
InputFormat is ORC only. However there can be metadataonly or empty result
optimizations on Acid tables, which change the input format to
NullRows/OneNullRowInputFormat, which gets tripped up on this check.
Relaxing this check to allow nullrows and onenullrow input formats.
