Question

我正在使用HDP 2.6安装Drill，在进行安装时，屏幕在选择奴隶代理时卡在一个屏幕上。

在日志文件中：

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.api.services.BaseService.handleRequest(BaseService.java:126)
    at org.apache.ambari.server.api.services.BaseService.handleRequest(BaseService.java:90)

早些时候，我已成功使用HDP 2.5进行测试，并且已从https://github.com/dvergari/ambari-drill-service下载了钻取自定义服务脚本。

请帮我解决这个问题。 HDP：2.6 Ambari：2.5

这个git repo有同样的问题...更改 metainfo.xml ，如下所示......
