我试图在Hive表（apache-hive-3.1.1）中插入一些值，并且出现Error Caching map.xml错误。 “显示表”工作正常，我可以在localhost：9870上看到hadoop集群。谁能告诉我如何解决此错误？
我已经厌倦了格式化NameNode并再次运行查询。我发现的其他选项是更改权限并删除hdfs数据。我找不到任何一种方法。
创建表运行得很好。
create table employees
(empid int,
firstname varchar(30),
lastname varchar(30),
tenure int,
address struct<street:string,city:string>,
subordinates array<string>);
以下内容无效，
insert into employees
select 1, "Vitthal","Srinivasan",1, named_struct("street","Bellandur","city","Bangalore"),array("Anuradha","Arun","Swetha")
union all select 2, "Swetha","Kolalapudi",4, named_struct("street","Bellandur","city","Bangalore"),array("Pradeep")
union all select 3, "Janani","Ravi",2, named_struct("street","Bellandur","city","Bangalore"),array("Navdeep")
union all select 4, "Navdeep","Singh",3, named_struct("street","Bellandur","city","Bangalore"),array("Shreya","Jitu");
下面是我收到的错误消息，
hive> insert into employees
> select 1, "Vitthal","Srinivasan",1, named_struct("street","Bellandur","city","Bangalore"),array("Anuradha","Arun","Swetha")
> union all select 2, "Swetha","Kolalapudi",4, named_struct("street","Bellandur","city","Bangalore"),array("Pradeep")
> union all select 3, "Janani","Ravi",2, named_struct("street","Bellandur","city","Bangalore"),array("Navdeep")
> union all select 4, "Navdeep","Singh",3, named_struct("street","Bellandur","city","Bangalore"),array("Shreya","Jitu");
