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.
