[jira] [Created] (HIVE-19681) Fix TestVectorIfStatement

Vihang Karajgaonkar created HIVE-19681:
------------------------------------------

             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.
