TisonKun opened a new pull request #10489: [FLINK-15134][client] Delete temporary files created in YarnClusterDescriptor
URL: https://github.com/apache/flink/pull/10489
 
 
   ## What is the purpose of the change
   
   We create temporary files for storing `flink-conf` & `JobGraph`. Although we ask for deleting them on exit, for a long running YarnClusterDescriptor it is possibly a resource leak. We can delete the file when they are no longer used. The delete hook will then silently fail on deletion but it is expected.
