How to add new yarn queue using Rest API / Ambari configs.sh script

[#1]

Hi Team,

Is there any way to add new queue using Yarn rest api ? or Ambari configs.sh script ?

I tried below link but no luck -

  "message" : "org.apache.ambari.server.controller.spi.UnsupportedPropertyException: The properties [items] specified in the request or predicate are not supported for the resource type Cluster."

When i tried to enable Developer Tools for Ambari View->Yarn queue manager , I see below call -

@Veerendra Nath Jasthi As I am adding queues programmatically, I am hesitant to call API on views ... I am calling refresh queues api as follows, for which I need to manually do the save and refresh.

curl -u uname:pwd -H "X-Requested-By:ambari" -iX POST -d '{

    "command" : "REFRESHQUEUES",

  },
