Question

我正在尝试使用Apache Kylin构建我的第一个多维数据集，一切正常，直到我收到错误的最后一步：

java.lang.IllegalStateException: Can't get cube source record count.

根据这个问题，https：// github.com/KylinOLAP/Kylin/issues/101发生错误，因为Kylin试图在hive的输出中找到这种模式：“HDFS读取：（\ d +）HDFS写入：（\ d + ）成功“。

我在Kylin的输出看起来已损坏：

但是，当我查看Hive日志时，它看起来没问题：

我正在使用Hortonworks Sandbox 2.2：

hadoop-2.6.0
hbase-0.98.12
hive-0.14.0
zookeeper-3.4.6

有人可以告诉我为什么我的麒麟日志预览看起来像这样，首先可能是上一步错误的原因吗？

Answer 1

几天前，麒麟开发者为此类问题提出了绕过协议

https://github.com/apache/incubator-kylin/commit/a4692dba681bc2f136e02c64565639eb0080fcc9

有时候，即使工作成功，hadoop也可能无法得到反击从现在开始，当未能获得立方体源时，Kylin会发出警告而不是错误。

我所要做的就是重建Kylin。
