No, bytearray constants are not supported. The reason for not supporting casts to bytearray is we would need a mechanism to describe how to do the casts (are strings stored as UTF-8 or something else, how are numeric values handled?) that we don't have.
The reason for not allowing a bytearray constant is we never found a use case. It seemed like strings always suffice. If you have a convincing use case where this isn't so, we could reconsider this. The one issue is that since Pig delegates casting of binary data to loaders, it would be impossible to cast this constant to anything else, since it wouldn't be associated with a loader. Alan.
