bing huang created KYLIN-1852:
---------------------------------
Summary: 在有distinct count时，cube 选择出错
Key: KYLIN-1852
URL: https://issues.apache.org/jira/browse/KYLIN-1852
Project: Kylin
Issue Type: Bug
Components: Query Engine
Affects Versions: v1.5.2
Environment: CentOS release 6.6
Reporter: bing huang
Assignee: liyang
问题描述：
同一个model 建立两个cube, 在这称为cube1 与 cube2. 两个cube有相同的measure,
除了cube2多一个distinct_count measure , 这儿称为
a 。
查询时使用 select count(distinct a) from table1. 这个时候查询出错，提示Can't create
EnumerableAggregate! 日志中查询选择的cube
为cube1 而不是cube2。 以下为详细日志：
