[jira] [Created] (KYLIN-2888) Subquery columns not exported in OLAPContext allColumns

Roger Shi created KYLIN-2888:
--------------------------------

             Summary: Subquery columns not exported in OLAPContext allColumns
                 Key: KYLIN-2888
                 URL: https://issues.apache.org/jira/browse/KYLIN-2888
             Project: Kylin
          Issue Type: Bug
            Reporter: Roger Shi


Query like this returns empty value, because olap context allColumns field isn't set rightly.

```sql
select c.COUNTRY, c.NAME,b.TRANS_ID, b.BUYER_ID from KYLIN_COUNTRY c join (
        select * from KYLIN_SALES s join KYLIN_ACCOUNT a on s.SELLER_ID = a.ACCOUNT_ID where a.ACCOUNT_ID <= 10000866
   ) b on b.ACCOUNT_COUNTRY = c.COUNTRY
```
