lsyldliu opened a new pull request, #20713:
URL: https://github.com/apache/flink/pull/20713

   ## What is the purpose of the change
   
   When enabling checkpoint, if using scalar UDF, the UDF  class will be loaded 
during generating JobGraph. But the UDF class is in the user classloader, we 
can't load it from thread context classloader, so we should use the user 
classloader to compile JobGraph when needed.
