             Summary: Delete temporary files created in YarnClusterDescriptor
                 Key: FLINK-15134
                 URL: https://issues.apache.org/jira/browse/FLINK-15134
             Project: Flink
          Issue Type: Improvement
          Components: Client / Job Submission
            Reporter: Zili Chen
            Assignee: Zili Chen
             Fix For: 1.10.0


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.
