------------------------------------------
Summary: 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
{{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.
