When I send sql query to Kylin like this:
select app_name, count(distinct uid) as uv from sdk_log left join week_calendar on sdk_log.day_time = week_calendar.week_cal where sdk_log.day_time = date '2016-05-01' group by app_name order by uv desc limit 200 and failed. So I have to restart Kylin. The dimension `app_name` is a great high cardinality. If I switch to `app_tag` dimension , it will return the right result. So I can’t get the top measure dimension in Kylin? If can, and what can I do to solve this? -------------------------------- 郑江雨 云平台 Phone: 15155195496
