Thejas M Nair commented on HIVE-18841:
--------------------------------------
Note that only permanent UDF are passed with this patch for authorization. That
would address the primary use cases for this feature (encryption related UDFs
provided by 3rd party vendors/cluster admins).
It doesn't make sense to do usage authorization for temporary UDF as the user
already has to have permissions to create them (you have to create it every
time to use it).
In case of built-in UDF, a lot of these UDFs are implicitly used (eg. cast one
type to another), so it doesn't make sense to authorize their usage, as it
would be very confusing for users.
