Tsz Wo (Nicholas), SZE updated HDFS-4513:
-----------------------------------------
Attachment: h4513_20130731.patch
Let's add a statement to say that the additional properties are optional. The
doc is about the WebHDFS REST API so that I think it is better not to mention a
specific implementation. Here is a new patch.
h4513_20130731.patch
> Clarify WebHDFS REST API that all JSON respsonses may contain additional
> properties

> 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.
