Json 从配置单元表检索数据时为空值

我想为这个json对象创建一个配置单元表

我的创建表查询是

CREATE EXTERNAL TABLE data (
query STRUCT<
        results: STRUCT<
                Result: ARRAY<
                        STRUCT<

                                Categories: STRING,
                                Title: STRING,

                                BusinessUrl: STRING,
                                State: STRING,
                                Url: STRING,

                                        LastReviewIntro: STRING,
                                        TotalReviews: STRING,
                                        TotalRatings: STRING,

                                Latitude: STRING,
                                Longitude: STRING

) ROW FORMAT SERDE 'org.openx.data.jsonserde.JsonSerDe' LOCATION '/user/hive/warehouse/test/';

我也试过不同的方法，比如

CREATE EXTERNAL TABLE data (
query string
) ROW FORMAT SERDE 'org.openx.data.jsonserde.JsonSerDe' LOCATION '/user/hive/warehouse/test/';

对于此select*语句，将显示所有结果。但是我上面的问题是什么

---

我还尝试了

从数据中选择get_json_对象（'data.query'，'$'）这也获取空值
 可能是因为类别是null而不是字符串。也许JsonSerDe会更宽容一点。
我的答案是，我们应该使用不同的jar来获取所有值

 ADD JAR /hive/Hive/hive-0.12.0/lib/hive-serdes-1.0-SNAPSHOT.jar;

在代码中，除了
行格式SERDE'com.cloudera.hive.SERDE.JSONSerDe'
之外，所有内容都是相同的。我们将获得嵌套块中的所有值

 ADD JAR /hive/Hive/hive-0.12.0/lib/hive-serdes-1.0-SNAPSHOT.jar;
