---------------------------------------------
> JsonSerDe: TBLPROPERTY treating nested json as String
> -----------------------------------------------------
>
> Key: HIVE-25541
> URL: https://issues.apache.org/jira/browse/HIVE-25541
> Project: Hive
> Issue Type: Bug
> Reporter: Panagiotis Garefalakis
> Assignee: Panagiotis Garefalakis
> Priority: Major
>
> Native Jsonserde 'org.apache.hive.hcatalog.data.JsonSerDe' currently does not
> support loading nested json into a string type directly. It requires the
> declaring the column as complex type (struct, map, array) to unpack nested
> json data.
> Even though the data field is not a valid JSON String type there is value
> treating it as plain String instead of throwing an exception as we currently
> do.
> {code:java}
> create table json_table(data string, messageid string, publish_time bigint,
> attributes string);
> {"data":{"H":{"event":"track_active","platform":"Android"},"B":{"device_type":"Phone","uuid":"[36ffec24-f6a4-4f5d-aa39-72e5513d2cae,11883bee-a7aa-4010-8a66-6c3c63a73f16]"}},"messageId":"2475185636801962","publish_time":1622514629783,"attributes":{"region":"IN"}}"}}
> {code}
> This JIRA introduces an extra Table property allowing to Stringify Complex
> JSON values instead of forcing the User to define the complete nested
> structure
