Edward Capriolo commented on HIVE-4937:
---------------------------------------
Marked this as a blocker because we should not do a release until this is
sorted out, but this does not need to be handler right away.
> Create description annotations for vectorized UDF

> Vectorized UDFs should technically be close to the same as normal UDFs, but
> that is not guaranteed. For example a standard UDF might have multiple
> overloads that the vectorized version does not.
> When users run things like 'describe function' they may not be getting the
> correct information depending if they are in vectorized mode or not.
> [~ehans] I assigned this to you feel free to unassign it, but I think we need
> some internal documentation for vectorized UDFs.
