-----------------------------
Summary: Kylin bitmap null pointer exception
Key: KYLIN-3416
URL: https://issues.apache.org/jira/browse/KYLIN-3416
Project: Kylin
Issue Type: Bug
Components: Query Engine
Affects Versions: v2.3.1
Reporter: Lemont
Hi,team:
Ithink there is a conflict between floor function and count distinct.
For example:
select
floor((1524931200 - biz_time)/(30*86400)),
count(DISTINCT id) id
from test
group by floor((1524931200 - biz_time)/(30*86400))
Caused by: java.lang.NullPointerException
