hadoop - Apache Kylin- “Timeout visiting cube”和其他怪异现象

Question

我已经在Kylin上安装了MapR发行版，并且一切正常
罚款到一定程度。我运行了sample.sh脚本，现在有了
“learning_kylin”项目，然后我可以在多维数据集和
该工作报告成功完成了100％。

但是..这样做之后，显示屏始终显示我的多维数据集为0.0
个字节，如果我从文档中运行示例查询，则会得到一个
“超时访问多维数据集”错误。

我注意到的另一个奇怪的事情是“构建”对话框是
显示今天日期的开始日期，我无法对其进行编辑。不确定
是否与我所看到的怪异有关，但是
谁能告诉我Kylin如何确定放置在那里的值(value)？

无论如何，对如何调试它的任何想法都将不胜感激。
我已经检查了日志，但没有发现任何东西跳到我的身旁
非常有用。这是我发现的:

编辑:使用hbase shell查看HBase，我可以看到Kylin肯定连接到HBase，至少足以创建表，而不是。但是，似乎是多维数据集的后备存储的表为空。
