Hive 我在选择配置单元中的结构数组时遇到问题

我已经阅读了网站上的所有示例，但没有一个适合我。我添加了砖厂UDF： 创建临时函数collect_struct作为“brickhouse.udf.collect.CollectUDAF”，并

我使用了来自和的示例

我的SQL：

我总是会遇到同样的错误：

失败：ClassCastException org.apache.hadoop.hive.serde2.objectinspector.StandardStructObjectInspector 不能投靠 org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector

有什么想法吗？

我使用的是Hive版本1.1.0，能够创建一个结构数组，而不需要Brickhouse jar文件的UDF。试试这个

SELECT house_id ,
       collect_list(named_struct("first_name", first_name, "last_name", last_name))
FROM house
GROUP BY house_id;

1   [{"first_name":"Bob","last_name":"jones"},{"first_name":"Jenny","last_name":"jones"}]   
2   [{"first_name":"Sally","last_name":"johnson"}]  
3   [{"first_name":"John","last_name":"smith"},{"first_name":"Barb","last_name":"smith"}]

请将您的完整堆栈跟踪与错误共享这是我得到的唯一错误：请转到您的JobTracker并跟踪您的hive作业的jobid。找到其中的日志，它应该会显示在不同节点上为不同尝试收集的详细日志。当你能找到他们时发布！配置单元不创建作业-它会立即失败：配置单元>选择房屋id>，从测试>按房屋id分组中收集名为first\u name、first\u name、last\u name、last\u name>；失败：ClassCastException org.apache.hadoop.hive.serde2.objectinspector.StandardStructObjectInspector无法强制转换为org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector hive>您解决了吗？我也看到了同样的问题。这完全有效。如上所述，不需要使用breakhouse jar文件

create temporary function collect as 'brickhouse.udf.collect.CollectUDAF';

CREATE TABLE test ( <br>
house_id bigint,<br>
first_name string,<br>
last_name string<br>
);

INSERT INTO test VALUES<br>
(1,"Bob","jones"),<br>
(1,"Jenny","jones"),<br>
(2,"Sally","johnson"),<br>
(3,"John","smith"),<br>
(3,"Barb","smith");

select house_id<br>
      ,collect(named_struct("first_name", first_name, "last_name", last_name))<br>
from test<br>
group by house_id;

SELECT house_id ,
       collect_list(named_struct("first_name", first_name, "last_name", last_name))
FROM house
GROUP BY house_id;

1   [{"first_name":"Bob","last_name":"jones"},{"first_name":"Jenny","last_name":"jones"}]   
2   [{"first_name":"Sally","last_name":"johnson"}]  
3   [{"first_name":"John","last_name":"smith"},{"first_name":"Barb","last_name":"smith"}]
