ElasticSearch & Graylog2 connection problem


I'm absolutely new with Graylog2 & ElasticSearch - so sorry if anything wrong.

After I installed it with that and that instructions - I got error when start it:

$ 2013-03-29 15:09:49,654 WARN : org.elasticsearch.discovery - [graylog2-server] waited for 30s and no initial state was set by the discovery
Exception in thread "main" org.elasticsearch.discovery.MasterNotDiscoveredException: waited for [30s]

Full debug-log available here.


# lsb_release -a
Description: Debian GNU/Linux 6.0.7 (squeeze)

Package: elasticsearch
Version: 0.20.6


Am I right understand that Graylog2-server cann't connect to ElasticSearch?

Can somebody please give any idea to fix it?
