DRILL作爲HDP 2.6的自定義服務：java.lang.ClassCastException

Question

我正在安裝Drill with HDP 2.6，並且在安裝過程中，屏幕停留在選擇從屬代理的一個屏幕上。

在日誌文件中：

java.lang.ClassCastException: java.util.LinkedHashSet cannot be cast to java.util.List 
    at org.apache.ambari.server.controller.internal.StackAdvisorResourceProvider.prepareStackAdvisorRequest(StackAdvisorResourceProvider.java:110) 
    at org.apache.ambari.server.controller.internal.ValidationResourceProvider.createResources(ValidationResourceProvider.java:81) 
    at org.apache.ambari.server.controller.internal.ClusterControllerImpl.createResources(ClusterControllerImpl.java:298) 
    at org.apache.ambari.server.api.services.persistence.PersistenceManagerImpl.create(PersistenceManagerImpl.java:97) 
    at org.apache.ambari.server.api.handlers.CreateHandler.persist(CreateHandler.java:37) 
    at org.apache.ambari.server.api.handlers.BaseManagementHandler.handleRequest(BaseManagementHandler.java:73) 
    at org.apache.ambari.server.api.services.BaseRequest.process(BaseRequest.java:144) 
    at org.apache.ambari.server.api.services.BaseService.handleRequest(BaseService.java:126) 
    at org.apache.ambari.server.api.services.BaseService.handleRequest(BaseService.java:90) 

早些時候，我已成功與HDP 2.5和鑽定製服務測試腳本已經從https://github.com/dvergari/ambari-drill-service下載。

請幫我解決這個問題。 HDP：2.6 Ambari：2.5
