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.
