v2.0.0-alpha.2: elasticsearch_node_name not displaying

[HillNet]

The elasticsearch_node_name does not appear to be parsed to elasticsearch. In ES (v2.2.0) I use the kopf plugin to view my cluster and nodes.

The node summary page looks like this:

The top 2 nodes are graylog nodes. Note they don't display their node name.

When I view their node stat's I see their name is not populated, refer below:

On an ES node it is populated, and the view node stat's looks like this:

Finally I have set "elasticsearch_node_name" in the server.conf file.

System is:
graylog v2 alpha2
ES 2.2.0
Ubuntu 64bit, 15.10

This seems to be a regression introduced in Elasticsearch 2.1.1. The node name is properly used in Elasticsearch 2.1.0. I'll investigate further.
