sparksql query result is not same as persto on same sql

[dylan]

hello all:
     i am use carbondata with 1.2.0,spark with  1.6.0.
     in my test case
   1.Creating a Table
  cc.sql("create table IF NOT EXISTS  test.table5(id string,name
String,city String,age int) stored by 'carbondata' *
tblproperties('DICTIONARY_INCLUDE' = 'age')* ")

  2.load csv data into table,data like this:
    id,name,city,age
    1,david,shenzhen,31
    88,eason,shenzhen,27
    3,jarry,wuhan,35
 
   3.select from sparksql,result is :
  +-----+--------+-----------+------+--+
| id  |  name  |   city    | age  |
+-----+--------+-----------+------+--+
| 1   | david  | shenzhen  | 31   |
| 3   | jarry  | wuhan     | 35   |
| 88  | eason  | shenzhen  | 27   |
+-----+--------+-----------+------+--+
   this result is correct

 4.select from presto,result is:
 id | name  |   city   | age
----+-------+----------+-----
 1  | david | shenzhen |   3
 3  | jarry | wuhan    |   4
 88 | eason | shenzhen |   2
(3 rows)
  look at the age field,is wrong
 
I know why this happens because I used dictionary encoding in the age field。

Can anyone help me with this problem?
