Nikesh commented on HIVE-15989:
-------------------------------
The data is stored in Azure Data lake in ORC format.
The data types I have tried are DOUBLE and DECIMAL(38,38) but both gave the
same result as 0.3333333333333333 instead of
0.3333333333333333333333333333333333333333.
> Incorrect rounding in decimal data types

> 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,
