Yum install 2.2 - repomd.xml not found

Hi All,
I'm trying to upgrade from 1.7 to 2.2 with the puppet module. It lays down the new elasticsearch.repo file but when it goes to retrieve the metadata I get a 404 not found. The same happens in the browser as well from this url:

http://packages.elastic.co/elasticsearch/2.2/centos/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found"
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: elasticsearch. Please verify its path and try again

Substituting 1.7 for 2.2 does retrieve the metadata file. Any ideas?

Thanks,
