问题描述
当我尝试将
mlPrintForestPlan 与 3 节点集群中的副本一起使用时，mlDatabasesWithForestsOnOneHost 出现错误。
# gradle-prod.properties
mlDatabasesWithForestsOnOneHost=myApp-modules,myApp-schemas,myApp-triggers
mlDatabaseNamesAndReplicaCounts=myApp-content,1,myApp-modules,myApp-triggers,1
mlPrintForestPlan 命令显示上述配置错误。我是否需要指定其他内容来仅在一台主机上设置数据库，并在另一台主机上设置副本？
./gradlew mlPrintForestPlan -Pdatabase=myApp-modules -PenvironmentName=prod
> Task :mlPrintForestPlan Failed

解决方法
如果它不起作用，这听起来像是一个未经测试的场景 - 只需在 ml-app-deployer 中创建一个新票证，以获取对为配置为仅在一台主机上具有森林的数据库创建副本的支持。
