chuxiao updated KYLIN-4606:
---------------------------
    Description: 
目前Kylin开启下推查询后，如果使用olap查询失败则会使用下推查询。如果下推也查询失败,返回下推的异常。但我们更关心olap的异常信息，希望返回给用户的是olap异常。

目前Kylin开启下推查询后，如果使用olap查询失败则会使用下推查询。如果下推也查询失败，记录错误日志并返回异常。但是返回的异常已经是下推的异常了，olap的异常信息丢了，不方便定位问题。添加olap查询异常的错误日志。)
        Summary: throw  olap exception when  olap query and pushdown both error 
 (was: add  olap query error logs when  olap query and pushdown both error)
