Description

According to Section 5.4 in http://tools.ietf.org/id/draft-zyp-json-schema-03.html, the default value of "additionalProperties" is an empty schema which allows any value for additional properties. Therefore, all WebHDFS JSON responses allow any additional property since the WebHDFS REST API do not specify additionalProperties.

However, it is better to clarify in the API that all JSON respsonses may contain additional properties.
