Hi:
Maybe you can try to set them as derived dimensions.
This document can help you learn more:

hello:
想问一下kylin是不是在国内也有开发公司，有没有可以有偿提供一些技术支持呢？因为我们在学校内在网上搜到的内容有点少，比如说我们的数据属性中有经纬度，在前端需要查询历史轨迹，这种放到维度上又会造成维度爆炸，hbase内存又会崩溃这种问题？
谢谢。

Or you can show the detailed log so that we can find out the root cause.

Hi,
Are you using Kylin4.0.0-alpha? As far as I know, CardinalityExecutable is
removed in Kylin4. If so, this error message can be ignored and I guess it will
be removed in next release.
