Elasticsearch basic client connection

问题

I have setup a SSH tunnel on port 9300 to my remote elasticsearch server.

When running this basic example to get the example data from the elasticsearch instance I get a "org.elasticsearch.client.transport.NoNodeAvailableException: No node available"

Settings settings = ImmutableSettings.settingsBuilder()
            .build();

    Client client = new TransportClient(settings).addTransportAddress(
            new InetSocketTransportAddress(InetAddress.getLocalHost().getHostName(), 9300));


    GetResponse getResponse = client.prepareGet("bank", "account", "25").execute().actionGet();

回答1:

my setup is that i connect from my localhost to a remote machine where elasticsearch is running in a docker-container and i got the same problem on port 9300 using transportclient with netty4. connecting to the tunneled port 9200 was no problem

transport.publish_host: localhost

has fixed it

so my es.yml has now:

http.host: 0.0.0.0
transport.host: 172.18.0.33
transport.publish_host: localhost

and i do the tunnel via:

ssh -N -L 9300:172.18.0.33:9300 user@server.com
