> Project: Hive
> Issue Type: Bug
> Components: UDF
> Reporter: Alexander Pivovarov

>
> Currently getTimestampValue casts Timestamp to Date and returns Date.
> Hive Timestamp types stores time with nanosecond precision.
> Timestamp class has getNanos method to extract nanoseconds.
> Date class has getTime method which retuns unix time in milliseconds.
> So, it order to be able to get nanoseconds from Timestamp fields GenericUDF
> getTimestampValue should return Timestamp instead of Date.
