Review comment:
I find actually there several test cases, such as GenericInMemoryCatalogTest
use a raw class String without real class definition. Using the assignable
class check either in CatalogFunctionImpl or test case will cause an extra code
change. To limit the scope of this PR, How about we keep it as now for the
consistency with how we handle generic lable of table and view in hive
catalog?
