Flink CDC中为什么只使用一个插槽，明明给他分配了八个？我设置了八个，但是任务只在一个上面跑，

Flink CDC中为什么只使用一个插槽，明明给他分配了八个？我设置了八个，但是任务只在一个上面跑，按道理这八个，都应该有数据流转啊，就是普通的MySQL到MySQL

flink web dashboard里，每个任务能单独下载吧？启动时也能看到是哪个日志文件，yarn不清楚，我是独立部署的，配置里日志文件名里有任务id这个变量，你可以看看yarn对应的日志配置文件里咋写的日志，flink对应yarn用的哪个配置文件知道吗？可以看看，我是独立部署的，用的是log4j.properties，我给改成自己的log4j.xml了
