does build-in UDF work with custom storage handler?

[Jie Zhang]

Hi,

I have an external table with custom storage handler. Somehow, when I use
build-in UDF (e.g. col >= unix_timestamp('2016-04-28 00:00:00') )in where
clause, the predicate does not do any filtering. if I used constant
literal, the predicate works fine.

May I know whether build-in UDF can work with custom storage handler in
hive? Thanks!
