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，直到出现错误的最后一步:
java.lang.IllegalStateException: Can't get cube source record count.

根据此问题https://github.com/KylinOLAP/Kylin/issues/101发生上述错误，因为Kylin尝试在配置单元的输出中找到此模式:“HDFS读取:(\ d +)HDFS写入:(\ d +)成功” 。
多维数据集构建教程的正确输出:github.com/KylinOLAP/Kylin/wiki/Kylin-Cube-Build-and-Job-Monitoring-Tutorial:

我在Kylin的输出看起来已损坏:

但是，当我检查Hive日志时，它看起来还不错:

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kylin日志预览看起来像这样，首先这可能是最后一步错误的原因吗？
最佳答案
几天前，麒麟开发人员针对此类问题提交了绕过
https://github.com/apache/incubator-kylin/commit/a4692dba681bc2f136e02c64565639eb0080fcc9
因为有时hadoop可能无法克服，即使工作成功
从现在开始，如果无法获取多维数据集源，则Kylin会发出警告而不是错误。
我要做的就是重建Kylin。
