[jira] [Created] (HIVE-23529) CTAS is broken for uniontype when row_deserialize

Mustafa Iman created HIVE-23529:
-----------------------------------

             Summary: CTAS is broken for uniontype when row_deserialize
                 Key: HIVE-23529
                 URL: https://issues.apache.org/jira/browse/HIVE-23529
             Project: Hive
          Issue Type: Bug
            Reporter: Mustafa Iman
            Assignee: Mustafa Iman


CTAS queries fail when there is a uniontype in source table and hive.vectorized.use.vector.serde.deserialize=false.

ObjectInspectorUtils.copyToStandardObject in ROW_DESERIALIZE path extracts the value from union type. However, VectorAssignRow expects a StandardUnion object causing ClassCastException for any CTAS query.
