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

             Summary: Add and Subtract should support date/timestamp and 
interval type
                 Key: SPARK-9133
                 URL: https://issues.apache.org/jira/browse/SPARK-9133
             Project: Spark
          Issue Type: Sub-task
            Reporter: Reynold Xin


Should support

date + interval
interval + date

timestamp + interval
interval + timestamp

The best way to support this is probably to resolve this to a date 
add/substract expression, rather than making add/subtract support these types.
