Pi Song commented on PIG-303:
-----------------------------
Is there really a scenario where users might want to cast a known type to
bytearray and cast it back? I think users should be more happy to always work
with the known type.
According to the Jira title, I guess if a user, for example, wants UTF-8
representation of Chararray, then he should use a UDF which returns ByteArray,
not casting.
My concern is that we shouldn't make LoadFunc more complex just to support an
operation which doesn't actually have a real use.
