Question

我已经使用MapR发行版安装了Kylin，事情似乎有效很好的一点。我运行了sample.sh脚本，现在我有了 “learning_kylin”项目，我可以在立方体上运行“构建” 工作报告100％完成成功。

但是......完成此操作后，显示屏始终将我的立方体显示为0.0 字节，如果我从文档中运行示例查询，我得到一个 “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，我无法编辑它。不确定如果这与我所见到的怪异有什么关系，但是谁能告诉我麒麟如何确定放在那里的价值？

无论如何，非常感谢任何有关如何调试此问题的想法。我已经检查了日志，但没有看到任何跳出来的东西非常有用。这是我发现的：

编辑：看看使用hbase shell的HBase，我可以看到Kylin肯定是连接到HBase，至少足以创建表和什么不是。但似乎是多维数据集的后备存储的表是空的。
