> Project: Hadoop Common
> Issue Type: Improvement
> Components: metrics

>
> JMXJsonServlet may provide a JSONP alternative to JSON to allow javascript in
> browser GUI to make requests.
> For security purpose about XSS, browser limit request on other
> domain[¹|#ref1] so that metrics from cluster nodes cannot be used in a full
> js interface.
> An example of this kind of dashboard is the bigdesk[²|#ref2] plugin for
> ElasticSearch.
> In order to achieve that the servlet should detect a GET parameter
> (callback=xxxx) and modify the response by surrounding the Json value with
> "xxxx(" and ");" [³|#ref3]
> value "xxxx" is variable and should be provide by client as callback
> parameter value.
