Elasticsearch on YARN problem to identify GLOBAL URI

Dear All,
I'm new on elastic search, so I'm sorry in advance if I'm doing some concectual error.

Following this guide https://www.elastic.co/guide/en/elasticsearch/hadoop/current/ey-usage.html
I installed and configured elastic serch running on Yarn, but now I have some doubt about.

after running this command
sudo hadoop jar elasticsearch-yarn-2.2.0-rc1.jar -start containers=3 app.queue=alpha container.mem=512

if I go on my http://master-ip-address:8088/cluster
i can see the application running

application_1454674969620_0082 root Elasticsearch-YARN ELASTICSEARCH alpha Wed Feb 10 13:03:29 0100 2016 N/A RUNNING UNDEFINED 4 4 1792 29.2 23.3
ApplicationMaster 0

Only if I read on log i can obtain information about the rest uri of the elasticsearch REST API
Below the log row

[2016-02-10 12:04:19,993][INFO ][http ] [Amphibius] publish_address {cluster-machine1-address:9201}, bound_addresses {[::]:9201}
[2016-02-10 12:04:20,001][INFO ][node ] [Amphibius] started

Now if I use a client REST I am able to call the api using the following address

if I restart the elastic-searc jar on yarn the address change and have some like this

There is a way to have a "kind of proxy manager" to invoke?
I mean I need a stable address to call.

Is there anybody that can help me.
Thanks in advance.

Unfortunately not and one of the reasons why the YARN integration is BETA.
YARN does not provide any provisioning or network/ip guarantees, data/node affinity - basically support for long running services (whether it's ES, mysql, postgres, you name it).
