vinoyang created FLINK-14655:
--------------------------------

             Summary: Change Type of Field jobStatusListeners from CopyOnWriteArrayList to ArrayList
                 Key: FLINK-14655
                 URL: https://issues.apache.org/jira/browse/FLINK-14655
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Coordination
            Reporter: vinoyang


After FLINK-11417, we made ExecutionGraph be a single-thread mode. It will no longer be plagued by concurrency issues. So, we can degenerate the current CopyOnWriteArrayList type of jobStatusListeners to a normal ArrayList type.
