Question

在两个ORC表上执行SMB连接，在subscription_id上进行bucketed和排序时，连接失败并给出以下错误：

任务跟踪器URL也没有提供太多细节。

查询是：

SELECT * FROM 
user_plays_buck
INNER JOIN small_user_subscription_buck
ON user_plays_buck.subscription_id = small_user_subscription_buck.subscription_id
LIMIT 1;

Answer 1

在Hive 1.1中得到了完全相同的问题。相同的查询在Hive 2.1中有效。所以升级你的蜂巢。

SMB加入不在Hive表上工作
