我正试图启动一个Druid主管来提取存储在hadoop中的Parqurt数据。但是，我收到以下错误，但找不到有关它的任何信息：

  

“错误”：“无法将类型ID'index_hadoop'解析为的子类型   [简单类型，类   io.druid.indexing.overlord.supervisor.SupervisorSpec]：已知类型ID   = [NoopSupervisorSpec，kafka] \ n，位于[来源：（org.eclipse.jetty.server.HttpInputOverHTTP）

我试图修复此问题，将hadoop深度存储，镶木地板和avro扩展加载到扩展加载列表中，但这不起作用。

这是我的主管JSON配置：
