[jira] [Created] (HIVE-15351) Disable vectorized VectorUDFAdaptor usage with non-column or constant parameters

Matt McCline created HIVE-15351:
-----------------------------------

             Summary: Disable vectorized VectorUDFAdaptor usage with non-column or constant parameters
                 Key: HIVE-15351
                 URL: https://issues.apache.org/jira/browse/HIVE-15351
             Project: Hive
          Issue Type: Bug
          Components: Hive
            Reporter: Matt McCline
            Assignee: Matt McCline
            Priority: Blocker


Vectorization using VectorUDFAdaptor is broken and produces wrong results when the parameter(s) have vectorized expressions that allocate scratch columns.  So, for now, we restrict VectorUDFAdaptor usage to columns or constant expressions.
