> Currently we can use rest API to retrieve all configuration properties per
> daemon, but unable to get a specific property by name. This causes extra
> parse work at client side when dealing with Hadoop configurations, and also
> it's quite over head to send all configuration in a http response over
> network. Propose to support following a {{name}} parameter in the http
> request, by issuing
> {code}
> curl --header "Accept:application/json"
> http://${RM_HOST}/conf?name=yarn.nodemanager.aux-services
> {code}
> get output
> {code}
> {"property"{"key":"yarn.resourcemanager.hostname","value":"${RM_HOST}","isFinal":false,"resource":"yarn-site.xml"}}
> {code}
> This change is fully backwards compatible.
