Java client handling connection failure

Mohit_Anchlia · April 11, 2014, 7:13pm

I am currently creating a client connection as shown below. One of the
questions I have is what is the right way to provide high availability and
reseliency on the client side when the node that I am connecting to fails?
Does this client automatically discovers all the nodes in the cluster and
retry on other nodes?

Client client = new TransportClient()

.addTransportAddress(new InetSocketTransportAddress("host1", 9300))

Hello Mohit ,

I am no expert in this , but i feel adding the sniff might help -

Settings settings = ImmutableSettings.settingsBuilder()
.put("cluster.name", clusterName)

.put("client.transport.sniff", true)*
.build();
TransportClient client = new TransportClient(settings);
client.addTransportAddresses(new InetSocketTransportAddress(esHost,
esPort));

Thanks
Vineeth

Yeah I looked at it but it only says that it's used as round robin. It
doesn't talk about reseliency during connection faiiures

The TransportClient uses a heartbeat signal every 5 secs to discover if the
node can still respond. If not, it will be dropped. "Sniffing" means, the
TransportClient can automatically connect to newly discovered nodes (e.g.
if the node comes up again, the client reconnects). The TransportClient
must be connected to at least one node all the time.
