Summary: 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 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 -- This message was sent by Atlassian Jira (v8.3.4#803005)
