To use this module:
1.) You will need to download the version of elasticsearch you are running and add it to the modules /files folder.
    http://www.elasticsearch.org/download/
2.) You will also need to download the elasticsearch service wrapper
    https://github.com/elasticsearch/elasticsearch-servicewrapper
    
Usage:

In your templates.pp or nodes.pp or wherever you define your server roles and applications you can call the elasticsearch module like so:

class role_prod_dbserver {
    class { elasticsearch: version => "0.15.2" }
}

This version number should correspond to the version of ES you downloaded from the above link.
The filenames should look like: 
/etc/puppet/modules/elasticsearch/files/elasticsearch-${version}.tar.gz 
- and -
/etc/puppet/modules/elasticsearch/files/elasticsearch-servicewrapper.tar.gz
