We are using Transport Client to connect to elastic search cluster with 6 nodes on aws. It is taking 3 minutes to connect. Can anyone help with the same ? Following is code snippet.
Settings settings = Settings.builder().put("cluster.name", clusterName).put("client.transport.sniff", true).build();
TransportAddress[] nodes = new InetSocketTransportAddress[addresses.length];
for (int idx = 0; idx < nodes.length; idx++) {
nodes[idx] = new InetSocketTransportAddress(InetAddress.getByName(addresses[idx]), port);
}
client = new PreBuiltTransportClient(settings).addTransportAddresses(nodes);
Logs are as follows
