Mark Wagner commented on HIVE-2482:
-----------------------------------
bq. I think we should not do this ^ lets make another UDF, or overload the
parameters of this one.
Is there any way to deprecate a UDF that will move people away from the current
'unhex'? The only difference from the updated version is that the current one
wraps the output in Text, so that it could be used by Hive before the binary
support. Now that there is binary support it doesn't make any sense for unhex
to wrap its output.

> * UDF's to convert to/from base64 string
