mlPrintForestPlan当我尝试mlDatabasesWithForestsOnOneHost在 3 节点集群中使用副本时出现错误。

# gradle-prod.properties
mlDatabasesWithForestsOnOneHost=myApp-modules,myApp-schemas,myApp-triggers
mlDatabaseNamesAndReplicaCounts=myApp-content,1,myApp-modules,1,myApp-schemas,1,myApp-triggers,1

该mlPrintForestPlan命令显示上述配置的错误。我是否需要指定其他内容才能仅在一台主机上设置数据库，而在另一台主机上设置副本？

./gradlew mlPrintForestPlan -Pdatabase=myApp-modules -PenvironmentName=prod
> Task :mlPrintForestPlan FAILED

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个主机上具有森林的数据库创建副本的支持。
