guoweiM opened a new pull request #9950: [FLINK-13993][runtime] Introduce the AbstractUserClassPathJobGraphRetriever
URL: https://github.com/apache/flink/pull/9950
 
 
   ## What is the purpose of the change
   
   Introduce the `AbstractUserClassPathJobGraphRetriever` which could construct the 'user code classpath' from the "job" dir. The `FileJobGraphRetriever` and `ClassPathJobGraphRetriever` could extend this abstract class and set the corresponding 'user code classpath' to the `JobGraph`.
   
   
   ## Brief change log
     - `AbstrctUserClassPathJobGraphRetriever` scan the 'jobdir' recursively and all the jar files in the 'jobdir' are added to the 'user code classpath'

     - Add `AbstractUserClassPathJobGraphRetrieverTest` to test the functionality.
