我已经在emr上创建了Hive表

create external table tests3(
transaction_id String,
order_id String,
user_id String,
amount String,
subscriber_number String,
product_type String,
provider String,
region String,
status String,
created_time String,
last_updated_time BIGINT,

)
row format 
    serde 'org.openx.data.jsonserde.JsonSerDe'
location 's3://locationtobucket';

当我从tests3中选择*时，我会得到记录。但是运行任何tez任务都会给我以下错误。

Query : select count(*) from tests3;
