> I have a numeric field in a file in my data lake and created a hive external 
> table pointing to this field. The field value is 
> 0.3333333333333333333333333333333333333333 but when I fetched this record 
> using the query it display only 0.3333333333333333. I tried using DECIMAL and 
> DOUBLE data types but nothing worked.is this a bug or am I not using the 
> exact data type for this?
> Thanks,
> NIkesh
