SELECT TRANSFORM / MAP / REDUCE to support optional ROW FORMAT
--------------------------------------------------------------

                 Key: HIVE-669
                 URL: https://issues.apache.org/jira/browse/HIVE-669
             Project: Hadoop Hive
          Issue Type: New Feature
          Components: Serializers/Deserializers
            Reporter: Zheng Shao


We should allow TRANSFORM / MAP/ REDUCE to accept optional ROW FORMAT:

{code}
SELECT TRANSFORM(a, b, c)
ROW FORMAT DELIMITED FIELDS TERMINATED BY '\001'
USING 'mypython.py'
AS (d STRING, e INT, f DOUBLE)
ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t'
{code}

Also, we should allow optional type information in the "AS" clause.
