> when we add some mask UDF on Decimal(18,10) type coloumn in hive-sdf moudle,
> the scale of the mask result value should be 10, but now is 18.
> In JavaHiveDecimalObjectInspector class the default scale of HiveDecimal is
> 18, so we need to change to the correct decimal precision on function
> toInspector(dataType: DataType) in HiveInspectors class.
>
> Can somebody fix it?
