Connecting remotely to elastic search cluster

Elastic Stack Elasticsearch
1

I am trying to connect remotely to elastic search cluster having 2 nodes
My question is I am able to query successfully only when we configure both
the cluster name and host name of the individual nodes? Why it doesn't work
if I only configure the cluster name in my client code

Settings settings = ImmutableSettings.settingsBuilder()
.put("cluster.name", "myClusterName").build();

Client client = new TransportClient(settings ).addTransportAddress(new InetSocketTransportAddress("host1", 9300))

    .addTransportAddress(new InetSocketTransportAddress("host2", 9300));

If you don’t want to define transport addresses, you’d better use a NodeClient.
A NodeClient is actually a node running inside the cluster (with auto discovery…) but without any data.

You just need to provide the cluster name with a NodeClient. See Elasticsearch Platform — Find real-time answers at scale | Elastic http://www.elasticsearch.org/guide/en/elasticsearch/client/java-api/current/client.html#node-client

Thanks David once again. Can you please help in deciding which one should I
go for NodeClient or TransportClient for production deployments.
From the Elasticsearch documentation what I understand is that Node client
eliminates the double hop that is present in Transport Client. Shall I opt
for Node client then? Please suggest.

I myself prefer TransportClient as it has absolutely no impact on the cluster state.
A new node joining the cluster generates a cluster state update which is propagated to all nodes.

I prefer having a very stable cluster state than continuous updates. Think about a Java batch which starts every minute and connect to the cluster to perform whatever action.
That would be a lot of events per day.

That’s why I mostly prefer using TransportClient.

My 2 cents.
