【报错】Hive：cannot be cast to org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector

Hive使用过程遇到报错：

Caused by: java.lang.ClassCastException: org.apache.hadoop.hive.serde2.objectinspector.StandardStructObjectInspector cannot be cast to org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector

解决：

排查后发现JOIN ON后面跟的多个条件链接字符是‘，’,改成‘and’即可。

类似这样：

select
    id
    ,name
from table1
left join
select
    id
    ,name
from table2
on (table1.id=table2.id and table1.name=table2.name)
