Thank you! return wrong result when 'SELECT SUM(dim1)' without set a relative metric of dim1. ---------------------------------------------------------------------------------- Key: KYLIN-3830 URL: https://issues.apache.org/jira/browse/KYLIN-3830 Project: Kylin Issue Type: Bug Affects Versions: v2.5.2 Reporter: Yuzhang QIU Priority: Major Hi, dear team: I design an cube1 based on table table1 with dim1, dim2, dim3.... and only one metric count(1), and 'SELECT SUM(dim1) FROM table1 group by dim2', Kylin process this SQL and return some result1. It seems ok. But as we know, Kylin don't store the detail data, the dimensions' members have been encoded and stored in Hbase as rowkey(cause I don't set any metric with an column). So, is the result1 right? Then, I clone cube1 to cube2, and set a metric SUM(dim1). the same SQL has been passed to kylin and got result2. It's different from result1 at the aggregation field. I also pass same SQL to hive and got result3, it's same with result2. Yes, I turn off the pushdown. I think there are some problems. I can't upload some picture of results for secret policy, sorry for that. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
