             Summary: Cast the column type for column masking
                 Key: HIVE-13486
                 URL: https://issues.apache.org/jira/browse/HIVE-13486
             Project: Hive
          Issue Type: Sub-task
            Reporter: Pengcheng Xiong
            Assignee: Pengcheng Xiong


Quoted from [~jdere] "in the case that getCellValueTransformer() returns a constant value (such as "NULL" to indicate the expression should be null), the resulting data type for that column ends up becoming the constant value NULL, which is different from the original column's type. Might want to add a type check somewhere to make sure the transformed expression and original expression match, or maybe wrap the transformed expression within a CAST to get the types to match."
