Review comment:
> What if we load a Hive UDF and it fail? Is it still going to show the
the method is missing in Spark?
Yea, since in hive mode use HiveSessionCatalog, user can use Spark's and
Hive's, we don't know user want to use which way(in other word, if we want to
know user's intention, it's hard and we need to add a lot code to judge). when
all failed show both error message, let user to know why make function failed
is enough
