在EMR中创建外部配置单元表后，如下所示：
create external table A . like
B
stored as orc
location 's3://s3table/';
然后尝试在其中插入一些数据：
insert overwrite table A
PARTITION(x,y,z)
select * from B distribute by y;
它给了我这个错误：

但是，如果我使用以下方法创建表A：
create external table A (
q decimal(38,18),name w string,e decimal(38,18))
PARTITIONED BY(x bigint,y bigint,z string)
STORED AS ORC
location 's3://s3table/‘;
工作正常。有人可以启发我吗？任何建议将不胜感激。
