【详述】搭建StarRocks实时同步Mysql组件，按照着Flink和StarRocks提供的官方文档执行到运行任务时，报错无法连接BE/CN节点
文档地址：https://nightlies.apache.org/flink/flink-cdc-docs-release-3.1/zh/docs/get-started/quickstart/mysql-to-starrocks/
我感觉和https://forum.mirrorship.cn/t/topic/5570是一个问题，但是我不知道怎么去修改重定向的host，也有可能没理解好。能教下我怎么处理吗？或者说明下。
【业务影响】无法同步数据
【是否存算分离】是
【StarRocks版本】例如：3.2.7
【集群规模】例如：1fe+1cn
【机器信息】16C32GB
