Robert Roland created HIVE-4519: ----------------------------------- Summary: JDBC getColumnTypeName() should respond with the Hive-specifc type name for ARRAY, STRUCT and MAP Key: HIVE-4519 URL: https://issues.apache.org/jira/browse/HIVE-4519 Project: Hive Issue Type: Bug Components: JDBC Affects Versions: 0.10.0 Reporter: Robert Roland
Per the Javadocs for ResultSetMetaData#getColumnTypeName(): "type name used by the database. If the column type is a user-defined type, then a fully-qualified type name is returned." Hive's type for array, struct and map is not String. It is array, struct or map, using a JSON string serialization. Returning the Hive type here will allow you to programmatically determine if you should parse the value in the ResultSet as JSON. ResultSetMetaData#getColumnType() should potentially return OTHER to indicate the column is a database-specific return type. This would replace the fix provided HIVE-1378. -- This message is automatically generated by JIRA.
