Elasticsearch Transport Client fails to recovery connection after cluster restart

Elastic Stack Elasticsearch
1

Hi,

I'm using Elasticsearch 5.4.0 with Transport Client with the following problems:

  • you must launch the application several times before it can connect to the cluster.

  • when connection is established, after a cluster restart, the connection is no more recovered, with this stack:

    NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{s-HKw1m4S9aMgCkx5iBuYg}{192.168.203.128}{192.168.203.128:9500}]]
    at org.elasticsearch.client.transport.TransportClientNodesService.ensureNodesAreAvailable(TransportClientNodesService.java:348)
    at org.elasticsearch.client.transport.TransportClientNodesService.execute(TransportClientNodesService.java:246)
    at org.elasticsearch.client.transport.TransportProxyClient.execute(TransportProxyClient.java:59)

    at org.elasticsearch.action.ActionRequestBuilder.execute(ActionRequestBuilder.java:54)
    at org.elasticsearch.action.ActionRequestBuilder.get(ActionRequestBuilder.java:69)

The Transport Client is setting as following:

            Settings.Builder settingsBuilder = Settings.builder();

		settingsBuilder.put("cluster.name", "globevmes5");
		settingsBuilder.put("client.transport.sniff", true);
		 	
		client = new PreBuiltTransportClient(settingsBuilder.build());
		try {
			client.addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("192.168.203.128"), 9500));
			
		} catch (Exception e) {
			System.out.println(e.getMessage());	
		}

and Elasticsearch tcp port is 9500.

With previous elasticsearch 5.3.2 it worked fine.

Any ideas to solve it?

Can you share the logs of the elasticsearch node?

Setting "client.transport.sniff" to false works fine.

thx

May be open an issue then?

I tried client.transport.sniff true and false and get the same issue. Node not available. Works fine in 5.3.2 TransportClient.

List nodes = client.connectedNodes();

This is empty....
