> Key: KYLIN-1274
> URL: https://issues.apache.org/jira/browse/KYLIN-1274
> Project: Kylin
> Issue Type: Bug
> Components: Driver - JDBC
> Affects Versions: v1.2
> Reporter: Yerui Sun

> Fix For: v2.0, v1.3

> How to produce this problem: create a query with the result over 10000 rows,
> and query with 'order by desc'. Check the first row, it's not the last row in
> all result, but a middle row, maybe the 10000th row.
> Checked the query log in kylin server, found 'Accept Partial: false',
> indicating it's indeed a partial query.
> The reason is, JDBC driver sent the QueryRequest with json encoding, and
> parsed into SQLRequest in server side. By default, QueryRequest only has sql
> and project parameters, and leave all other attributes as default in
> SQLRequest, and in SQLRequest, acceptPartial is true. That's why the query
> was processed as a partial query.
> The solution to solve this is simple, add acceptPartial as false in
> QueryRequest, and update JDBC driver.
