我对在hive上使用json数据还不熟悉。我正在开发一个spark应用程序，它获取json数据并将其存储到配置单元表中。我有这样一个json：

展开后如下所示：

我能够将json读入Dataframe并将其保存在hdfs上的某个位置。但是让Hive能够读取数据是很困难的。
例如，我在网上搜索之后，就尝试这样做：
使用 STRUCT 然后使用 column.element .
例如： web_app_security 将是（类型）列的名称 STRUCT )在table里面还有其他的JSON config_web_cms_authentication, web_threat_intel_alert_external 也将是structs（带 rating 以及 rating_numeric 就像田野一样）。
我尝试用json-serde创建表。以下是我的表定义：

CREATE EXTERNAL TABLE jsons (
web_app_security struct<config_web_cms_authentication: struct<rating: string, rating_numeric: float>, web_threat_intel_alert_external: struct<rating: string, rating_numeric: float>, web_http_security_headers: struct<rating: string, rating_numeric: float>, rating: string, rating_numeric: float>,
dns_security struct<domain_hijacking_protection: struct<rating: string, rating_numeric: float>, rating: string, rating_numeric: float, dns_hosting_providers: struct<rating:string, rating_numeric: float>>,
email_security struct<rating: string, email_encryption_enabled: struct<rating: string, rating_numeric: float>, rating_numeric: float, email_hosting_providers: struct<rating: string, rating_numeric: float>, email_authentication: struct<rating: string, rating_numeric: float>>,
threat_intell struct<rating: string, threat_intel_alert_internal_3: struct<rating: string, rating_numeric: float>, threat_intel_alert_internal_1: struct<rating: string, rating_numeric: float>, rating_numeric: float,  threat_intel_alert_internal_12: struct<rating: string, rating_numeric: float>, threat_intel_alert_internal_6: struct<rating: string, rating_numeric: float>>,

)ROW FORMAT SERDE 'org.openx.data.jsonserde.JsonSerDe'
STORED AS orc
LOCATION 'hdfs://nameservice1/data/gis/final/rr_current_analysis'

我试着用json serde解析这些行。在我将一些数据保存到表中之后，当我尝试查询它时，会出现以下错误：

Error: java.io.IOException: java.lang.ClassCastException: org.apache.hadoop.hive.ql.io.orc.OrcStruct cannot be cast to org.apache.hadoop.io.Text (state=,code=0)

我不确定我做得对不对。
我对将数据存储到表中的任何其他方法也持开放态度。任何帮助都将不胜感激。谢谢您。
