--------------------------------------
Hello [~liuml07]
I just uploaded v6 patch according to your comments. The patch should have
addressed Steve's concerns, I've replied and hopefully he can confirm that.
Also the plain text support will be tracked via ticket HADOOP-13639.
Thanks
> Support to retrieve specific property from configuration via REST API

> 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.
