Describe the bug
Flink流处理任务启动后 dolphinscheduler中的任务状态变为完成，但是Flink任务，还在运行并未执行完毕或关闭

After the Flink stream processing task is started, the task status in the dolphinscheduler becomes complete, but the Flink task is still running or not closed.

`private String findAppId(String line) {
    Matcher matcher = APPLICATION_REGEX.matcher(line);
   // 此处应去掉checkFindApp(line) 判断条件
  // The checkFindApp(line) condition should be removed here.
    if (matcher.find() && checkFindApp(line)) {
        return matcher.group();
    }
    return null;
}`
