Venkata Ramana G created CARBONDATA-138:
-------------------------------------------

             Summary: Scale up value of Avg aggregation for decimal type keeping sync with hive
                 Key: CARBONDATA-138
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-138
             Project: CarbonData
          Issue Type: Bug
            Reporter: Venkata Ramana G
            Priority: Minor


when we do avg aggregation for decimal type:
hive wiil update the precision of the avg result. 
e.g: Avg(decimal(30,10)), the result will be cast to decimal(34, 14)
so, carbon should keep the sync with hive, also need to improve the precision
by scaling up.
