我需要使用这个 json 对象数组在 hive 中创建外部表，为此我正在尝试这个不起作用的查询，请帮助我完成这个查询。
ADD JAR json-serde-1.1.9.2-Hive13.jar;
CREATE EXTERNAL TABLE mobile_structuring_table(
id int,
createdBy string,
status string,
utcTime string,
placeName string,
longitude double,
latitude double,
createdDate string,
accuracy string,
loginType string,
mobileNo string
)
ROW FORMAT SERDE 'org.openx.data.jsonserde.JsonSerDe'
LOCATION '/user/root/mobile_data/rest_api_mobile_data.json'
;
是这种 json 对象数组所需的任何特定 serde。

有错误可以分享吗？

表正在创建，但是一旦您在 hcataloge 中打开它，它就会发出以下错误
java.io.IOException: org.apache.hadoop.hive.serde2.SerDeException: Row is not a valid JSON Object - JSONException: Missing value at 1 [character 2 line 1]因此表正在创建但没有用。
