-------------------------------
Summary: Support percentile function after aggregate sub query
Key: KYLIN-5117
URL: https://issues.apache.org/jira/browse/KYLIN-5117
Project: Kylin
Issue Type: New Feature
Affects Versions: v4.0.0
Reporter: hujiahua
The following query execution will report an error：
java.lang.IllegalArgumentException: Unsupported function name PERCENTILE_APPROX
while executing SQL: "select percentile(t.gmv, 0.5) from ( select
buyer_id,sum(price) as gmv from kylin_sales group by buyer_id ) t"
The sql query:
select percentile(t.gmv, 0.5) from ( select buyer_id,sum(price) as gmv from
kylin_sales group by buyer_id ) t
It's better to support `percentile` function after aggregate sub query.
