#### 3] Check es version:

[acp@localhost bigdesk]$ curl -XGET 'http://127.0.0.1:9200/'
{
  "ok" : true,
  "name" : "Astaroth / Asteroth",
  "version" : {
    "number" : "0.17.9",
    "date" : "2011-10-19T22:08:24",
    "snapshot_build" : false
  },

#### 4] Try to access plugin...

[acp@localhost bigdesk]$ curl -XGET 'http://127.0.0.1:9200/_plugin/bigdesk/'
[acp@localhost bigdesk]$ 

(Identical behavior for elasticsearch-head)
