His cluster name is not right , because it is my cluster name
If you did not change the cluster name , it is the default one : elasticsearch
Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name", "elasticsearch").build();
2014-03-21 12:28 GMT+01:00 David Pilato david@pilato.fr:
Works fine for me.
Either your elasticsearch is not running locally, or your cluster name is not vesseltrackerES or you have some firewall issues.

Hi Georgi Ivanov,
yes,i am able to understand the Exception i.e. UnresolvedAddressException,but you are telling that to make sure host1 and host2 are resolved by adding entries to /etc/hosts to wherever the file in on Windows,for this can you give me the steps how to approach this.Sorry i am new to this and am learning i am unable to get the proper example.Thanks in advance for the help.
On Thursday, March 20, 2014 2:36:10 AM UTC+5:30, Georgi Ivanov wrote:
Well
I think UnresolvedAddressException obviously means that your Java client can not resolve host1 and host2
make sure host1 and host2 are resolvable by adding entries to /etc/hosts ot wherever the file in on Windows

Hi,
I am Y.Venu,i am totally new to this elasticsearch,now i am trying to communicate java elastisearch,i have gone through the elasticsearch java api's
1st i came across maven repositry.
i have created pom.xml in my eclipse and in the dependency tag i have just placed the code that i found in maven repositry
i.e.
org.elasticsearch
elasticsearch
${es.version}
After that i have created one class with the main method and i copied and placed the code that i found in the client api of elasticsearch i.e.
TransportClient.
main()
{
Client client = new TransportClient()
.addTransportAddress(new InetSocketTransportAddress("host1", 9200))
.addTransportAddress(new InetSocketTransportAddress("host2", 9200));
// on shutdown
client.close();
Settings settings = ImmutableSettings.settingsBuilder()
.put("client.transport.sniff", true).build();
TransportClient client1 = new TransportClient(settings);
}
After running this app javapplication,i am getting the errors like this

from this i came to know that there is problem in Maven Repositry,but i checked the maven,i din't find nay issues.
Was i am in the correct path to get the communication from java to elasticsearch.do i need to set any classpath or path related to elastic search.
any basic application so that i can look and get some idea.
URGENT PLZ
Thanks in advance.
