Edward Capriolo commented on HIVE-2482:
---------------------------------------
I was going to say:
This is an incompatible change because the return type of unhex has been
changed from string to binary
I think we should not do this ^ lets make another UDF, or overload the
parameters of this one.
> Convenience UDFs for binary data type
