Hive 只读取一行 json

Question

我有一个像这样的 json

[{"event": "1", "meta": {"name":"Kumar","":"28"}}, {"event": "2", "meta": {"name":"Harsh","":"27"}}]

I removed the square bracket as in hive it is giving error org.apache.hadoop.hive.serde2.SerDeException: java.io.IOException: Start token not found where expected

{"event": "1", "meta": {"name":"Kumar","":"28"}}, {"event": "2", "meta": {"name":"Harsh","":"27"}}

我正在像这样创建我的表

create external table record_two(event string,meta struct<name:string,age:string>)
ROW FORMAT SERDE 'org.apache.hcatalog.data.JsonSerDe'
LOCATION '/test/event_two/'; 

该表已创建但是当我运行 select 它只返回一条记录

Answer 1

记录应位于数据文件中的单独行中。

{"event": "1", "meta": {"name":"Kumar","age":"28"}}
{"event": "2", "meta": {"name":"Harsh","age":"27"}}

记录之间没有逗号，只有换行符。
