我创建了下表来访问上面的json数据。
create EXTERNAL table kccdata1 (
Response string,
data array<struct<
Season:STRING,
Sector:STRING,
Category:STRING,
Crop:STRING,
QueryType:STRING,
QueryText:string,
KCCAns:string,
StateName:string,
DistrictName:string,
BlockName:string,
SubmitDate:string>>)
row format serde "org.apache.hive.hcatalog.data.JsonSerDe"
location "/user/hduser/jsondata";
此表将每个结构作为每个记录的值。我可以使用下面的查询来访问它中的元素。
select data[0].querytype from kccdata1;
select data.season[1] from kccdata1;
但是，如果我想找到像crop =其他所有扇区的东西，我无法使用此表格来完成。 对此有任何建议都会有很大帮助。感谢。
