But it sounds like your client is using another cluster name [1].
Do you have any elasticsearch.yml in your project classpath?

Hi David,

Setting the (default) clustername, elasticsearch, doesn't help.

grtz, Koen

You need to set the cluster name I think.

My 2 cents

Hi,

I've troubles to connect a second client-only Node via the Java API to a remote 
cluster.

The first client (configured as client-only hence no master and no data) runs 
fine on localhost:9300. However, when the second client-only node tries to 
connect to the cluster an exception gets thrown:

org.elasticsearch.cluster.block.ClusterBlockException: blocked by: 
[SERVICE_UNAVAILABLE/1/state not recovered / 
initialized];[SERVICE_UNAVAILABLE/2/no master];

I use the following code to connect both clients:

            Node node = NodeBuilder.nodeBuilder().client(true).node();
            Client client = node.client();

            GetResponse response = client.prepareGet("twitter", "tweet", 
"1").execute().actionGet();
            LOGGER.info(response.getSourceAsString());

            // on shutdown
            node.close();

While the second client tries to join the cluster, the logs of the first client 
show the following warnings:

o.e.d.z.p.multicast [WARN] [Odin] received ping response ping_response{target 
[[Firebolt][DqdgEEe8RwSyVDUuqmQw4w][p2][inet[/192.168.2.21:9300]]], master 
[[Firebolt][DqdgEEe8RwSyVDUuqmQw4w][p2][inet[/192.168.2.21:9300]]], 
cluster_name[elasticsearch]} with no matching id [1]

I assumed that the first client would be running on localhost:9300 and the 
second one would bind to localhost:9301, but doesn't do that automatically. Do 
I need to specify an additional setting to allow this scenario?

(I also tested by adding a TransportClient instead of a Node and this works 
fine)

JUnit test code and log output can be found at:

Thx, Koen
