–data-dir="/data/tidb/data/cdc-8300" \

对比5.0.1版本ticdc的启动脚本run_cdc.sh多出了data-dir参数

tiup的版本是v1.5.0,以前用v1.4.1部署的tidb5.0.1在文件run_cdc.sh没有data-dir配置项

经过分析验证是tiup的组件cluster1.5.0版本的问题,它会在run_cdc.sh增加配置项data-dir,而ticdc不支持此配置项,如果将cluster回退到1.4.x版本就没问题了

我也遇到同样的问题。。。。
请问:如何回退 tiup cluster 版本呀。

先删除 tiup uninstall cluster:v1.5.0
然后tiup list cluster检查一下,没有的话安装 tiup install cluster:v1.4.1

升级到 v1.5.1 应该就可以了,多谢。
