Hello,

I'm trying to setup two elasticsearch nodes in Amazon they are in the same  
region.  
My configuiration is:  
discovery.type: ec2  
cloud.aws.access\_key:   
cloud.aws.secret\_key:   
discovery.ec2.ping\_timeout: 5m  
cloud.aws.region: eu-west-1  
discovery.ec2.host\_type: private\_ip  
discovery.ec2.tag.communication: es\_test

They find each other and connect OK.

Then I stated testing failover. Here are my settings:

elasticsearch.hosts=host1,host2  
elasticsearch.indexName=index1  
elasticsearch.indexType=dv  
elasticsearch.cluster=AMZ\_TEST

and I start the transport client in my application:

private @Value("${elasticsearch.hosts}") String esHosts;  
private @Value("${elasticsearch.cluster}") String clusterName;  
private TransportClient client;

```
public Client initClient() {
    Settings settings = ImmutableSettings.settingsBuilder()
            .put("cluster.name", clusterName).build();

    client = new TransportClient(settings);

        for (String hostname : esHosts.split(",")) {
            client.addTransportAddress(new 

```

InetSocketTransportAddress(hostname, 9300));  
}

```
    return client;
}

```

It all works fine and if I stop one node everything works.  
The problem is when I start the node again. I get this exception when I try  
to do any query:

Exception in thread "main"  
org.elasticsearch.transport.TransportSerializationException: Failed to  
deserialize exception response from stream

A few seconds after the two nodes find each other everything is ok.  
Is there anything I should do not to have this downtime.

Thank you

Hi,

Are you able to share your logs around the Exception? Just so we can see  
what's going on leading up to it.

Hi,

this error usually occurs if you have different JVM versions between server  
and client, or, if a plugin throws a custom exception at server side which  
is not present at the client, so it fails to decode the exception.
