Subject [jira] [Updated] (HDFS-4513) Clarify WebHDFS REST API that all JSON respsonses may contain additional properties
Date Tue, 30 Jul 2013 23:33:49 GMT

     [ https://issues.apache.org/jira/browse/HDFS-4513?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

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.

> 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.
