Connect my code with elasticsearch - scala

Question

I have an elasticsearch server installed in a machine:
this is a part of config:
transport: {
bound_address: inet[/192.168.1.42:9300]
publish_address: inet[/192.168.1.42:9300]
}
http: {
bound_address: inet[/192.168.1.42:9200]
publish_address: inet[/192.168.1.42:9200]
max_content_length_in_bytes: 104857600
}
And I try from Scala program with elasticsearch java library to connect to this server.
This is a code for connect to server using nodeBuilder :
val builder:Node = nodeBuilder()
.client(true)
.local(false)
.loadConfigSettings(false)
.clusterName("elasticsearch")
.settings(
ImmutableSettings.settingsBuilder()
//.put("network.bind_host", "192.168.1.42")
.put("network.host", "192.168.1.42")
.put("transport.tcp.port",9300)
.put("http.port",9200)
.build()
).node()
val client:Client = builder.client()
but receive this exception:

If I try to connect with this code works well:
val client:Client = new TransportClient()
.addTransportAddress(new InetSocketTransportAddress("192.168.1.42", 9300))
but i want connect with node client and not with TransportClient.
What do the error?
thank you very much

Answer 1

Strip the hostname and port out from the node client. A node client is a node in its own right, so setting the hostname/port to another node is why you have a clash (manifested in the bind exception).
val builder:Node = nodeBuilder()
.client(true)
.local(false)
.loadConfigSettings(false)
.clusterName("elasticsearch")
.node()
val client:Client = builder.client()
A node joins the cluster. A transport client just connects to a node.
