ok，but how should we consider application mode? Code generation works in server
,util parsing catalog function,we do not know where is the resource file
stored，so we can't ship the udf resource to cluster in advance.
The document solution is add the interface `JobbGraph#addClasspath`， but if
this path is a remote path，can the userCodeClassLoader load class from remote?
