Alexander Pivovarov commented on HIVE-10580:
--------------------------------------------
GenericUDF is a base class to build UDFs. Some 3rd party UDFs might have bigint
constants.
getConstantLongValue API was added to hive-1.2.0
I do not think it's a good idea to remove this API in 1.3.0.
Some people might built UDFs which uses getConstantLongValue already
> Fix impossible cast in GenericUDF.getConstantLongValue
