问题：FlinkCDC 3.1.0 pipeline 与 Flink 1.17.0 可能是因为出现版本不支持的问题（已实测）

持续报错：

原因：初步判断是由于flinkcdc不同开发团队使用的flink-cdc-pipeline-connector-doris-3.1.0.jar包内是基于判断flink-1.17.0/conf/config.yaml的flink conf文件而导致，而实际上1.17版本的flink conf/下只有flink-conf.yaml配置文件，在参考原配置手动添加config.yaml文件后仍然无效

解决：重新安装flinkcdc 3.1.0适配的flink版本 1.18，为官方推荐，而flink 1.19虽然是当前20240614的最新stable版本，但是阿里云开发者flinkcdc钉群社区中似乎还是有出现部分问题的可能，所以还是采用flinkcdc官方推荐的flink版本最佳
