------------------------------

             Summary: Vectorization: Custom UDF Vectorization annotations are ignored
                 Key: HIVE-14155
                 URL: https://issues.apache.org/jira/browse/HIVE-14155
             Project: Hive
          Issue Type: Bug
          Components: UDF, Vectorization
    Affects Versions: 2.2.0
            Reporter: Gopal V
            Assignee: Gopal V


{code}
@VectorizedExpressions(value = { VectorStringRot13.class })
{code}

in a custom UDF Is ignored because the check for annotations happens after custom UDF detection.

The custom UDF codepath is on the fail-over track of annotation lookups, so the detection
during validation of SEL is sufficient, instead of during expression creation.
