我已经安装了带有 MapR 发行版的 Kylin，在某种程度上，一切似乎都很好。我运行了 sample.sh 脚本，现在我有了“learning_kylin”项目，我可以在多维数据集上运行“build”，并且作业报告成功 100% 完成。
但是.. 这样做之后，显示器总是将我的多维数据集显示为 0.0 字节，如果我从文档中运行示例查询，我会收到“超时访问多维数据集”错误。
我注意到的另一件奇怪的事情是，“构建”对话框显示了今天日期的开始日期，我无法对其进行编辑。不确定这是否与我所看到的怪异有关，但谁能告诉我 Kylin 如何确定放在那里的价值？
无论如何，非常感谢有关如何调试它的任何想法。我检查了日志，但没有看到任何对我来说非常有用的东西。这是我发现的：

编辑：用 hbase shell 查看 HBase，我可以看到 Kylin 肯定连接到 HBase，至少足以创建表等等。但是看起来是多维数据集的后备存储的表是空的。
