----------------------------------------
Resolution: Invalid
> Fix TestVectorIfStatement
> -------------------------
>
> Key: HIVE-19681
> URL: https://issues.apache.org/jira/browse/HIVE-19681
> Project: Hive
> Issue Type: Test
> Components: Vectorization
> Affects Versions: 3.1.0, 4.0.0
> Reporter: Vihang Karajgaonkar
> Assignee: Vihang Karajgaonkar
> Priority: Major
>
> {{TestVectorIfStatement}} generates interesting batches (injection of random
> repeating null column values and repeating non-null values) when evaluating
> the vectorized expressions. But the modification of random rows is done after
> the row mode is evaluated. Hence it is likely that comparison results will
> fail. I am not sure how its working in the first place.
