> Key: KYLIN-3946
> URL: https://issues.apache.org/jira/browse/KYLIN-3946
> Project: Kylin
> Issue Type: Bug
> Components: Query Engine
> Reporter: Chao Long
> Assignee: Chao Long
> Priority: Major
> Fix For: Future
>
>
> Before, avg(col) will use sum(col)/count(1) to calculate.
> After including count column aggregation KYLIN-3883, avg(col) will use
> sum(col)/count(col) to calculate.
> If there is no predefined count(col) measure, query with avg(col) will get
> exception "NoRealizationFoundException: No realization found for
> OLAPContext", which will effect the query on old cubes. So we should consider
> compatibility.
