一、问题

在kylin页面执行查询语句时报错 Coprocessor resource limit exceeded: scanned bytes 3221248531 exceeds threshold 3221225472

版本：

kylin 2.6.1

查询语句：

select distinct control_zone from VIEW_CUBE_3U_FLIGHT_ROUTE_20210204 LIMIT 1000

报错日志：

二、解决

kylin jira里找到一些有用信息
https://issues.apache.org/jira/browse/KYLIN-2438

这里提到了1个参数

kylin.storage.partition.max-scan-bytes

去官网查了查，发现这个值的默认值就是日志里提示的阈值
在这里插入图片描述
kylin.properties

## The maximum number of bytes each coprocessor is allowed to scan.
## To allow arbitrary large scan, you can set it to 0.
#kylin.storage.partition.max-scan-bytes=3221225472

每个协处理器允许扫描的最大值，允许任意大小的scan，可以设置为0

根据配置文件里的提示，设置为0，查询已可以返回结果

总结：

查询返回的字节数超过了默认值

PS:kylin不适合查明细的场景，以后查询明细需要考虑一下Apache Doris、Clickhouse
