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.

What is the value of ${es.version}

Did you set it? Try with 1.0.1  
Also transport layer uses 9300 ports and not 9200 ports (REST layer)

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.

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.

Thankyou for the reply.I am not getting any errors,but i am not able to  
connect to my elasticsearch using java.Here my code.

import java.net.InetSocketAddress;

import org.elasticsearch.client.Client;  
import org.elasticsearch.client.transport.TransportClient;  
import org.elasticsearch.common.transport.InetSocketTransportAddress;

public class JavaES\_Client {

```
void function()
{
    //on StartUp
            System.out.println("In Function");
    
    Client client = new TransportClient()
    .addTransportAddress(new InetSocketTransportAddress("localhost", 

```

9200)); // This is where my control is getting stuck,without any  
exceptions or errors.

```
    System.out.println("Connected");
    //on ShutDown
    client.close();
}

public static void main(String[] args) {
    
    System.out.println("In Main Method");
    JavaES_Client jc = new JavaES_Client();
    System.out.println("Object Created");
    jc.function();
    
}

```

}

</div>

you can find my elasticsearch window i.e overview window and browse window.  
my java code you can see below.

from these windows i think you can get what i am doing.  
i just create new indexes with type and their id simply .  
before this i din't created any cluster or any node e.t.c. ,from my  
knowledge i have not created,but from ES site i came to know that cluster  
will be created bydefault and node aswell,but i have not given any cluster  
name or any specific thing or nodes.

i think i am not making any complication about this.

but to be frank..i am moving here and there like a child to know what is  
happening.

Java Code

import java.net.InetSocketAddress;  
import java.util.HashSet;  
import java.util.Set;

import org.elasticsearch.client.Client;  
import org.elasticsearch.client.transport.TransportClient;  
import org.elasticsearch.cluster.node.DiscoveryNode;  
import org.elasticsearch.common.settings.ImmutableSettings;  
import org.elasticsearch.common.settings.Settings;  
import org.elasticsearch.common.transport.InetSocketTransportAddress;

public class JavaES\_Client {

```
Client client;
Set<String> hosts;

void function()
{
    //on StartUp
            System.out.println("In Function");
    
client = new TransportClient()
    .addTransportAddress(new InetSocketTransportAddress("localhost", 

```

9300));

```
    System.out.println("Connected");
    //on ShutDown
    client.close();
}

 void connectES() {
    hosts = new HashSet<String>();
      hosts.add("locolhost");
    // hosts.add("host2.host1.mydomain.com"); // Make sure this 

```

resolvs to proper IP address  
Settings settings =  
ImmutableSettings.settingsBuilder().put("cluster.name",  
"vesseltrackerES").build();

```
      TransportClient transportClient = new TransportClient(settings);
      for (String host : this.hosts) {
    transportClient = transportClient.addTransportAddress(new 

```

InetSocketTransportAddress(host, 9200));  
}

```
      System.out.print("Connected to nodes : ");
      for (DiscoveryNode node : transportClient.connectedNodes()) {
    System.out.print(node.getName() + " , ");
      }
      System.out.println("");

      this.client = (Client) transportClient;
    }

public static void main(String[] args) {
    
    System.out.println("In Main Method");
    JavaES_Client jc = new JavaES_Client();
    System.out.println("Object Created");
// jc.function();
    jc.connectES();
    
}

```

}

you can find my elasticsearch window i.e overview window and browse window.  
my java code you can see below.

from these windows i think you can get what i am doing.  
i just create new indexes with type and their id simply .  
before this i din't created any cluster or any node e.t.c. ,from my knowledge i have not created,but from ES site i came to know that cluster will be created bydefault and node aswell,but i have not given any cluster name or any specific thing or nodes.

i think i am not making any complication about this.

but to be frank..i am moving here and there like a child to know what is happening.

There is something wrong with your set-up

How many ES node s you have ?  
On which IP addresses are ES hosts listening ?

I understood you have 2 hosts , but it seems you have only one on your local machine .

This is the code (a bit modified) I am using at the moment

public void connectES() {  
Set hosts = new HashSet();  
hosts.add("[host1.mydomain.com](http://host1.mydomain.com)");  
hosts.add("[host2.host1.mydomain.com](http://host2.host1.mydomain.com)"); // Make sure this resolvs to proper IP address  
Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name", "vesseltrackerES").build();

TransportClient transportClient = new TransportClient(settings);  
for (String host : this.hosts) {  
transportClient = transportClient.addTransportAddress(new InetSocketTransportAddress(host, 9300));  
}

System.out.print("Connected to nodes : ");  
for (DiscoveryNode node : transportClient.connectedNodes()) {  
System.out.print(node.getHostName() + " , ");  
}  
System.out.println("");

this.client = (Client) transportClient;  
}

Make sure that 192.168.1.100/101 is the right IP address of the host1/host2

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

Works fine for me.

Either your elasticsearch is not running locally, or your cluster name is not vesseltrackerES or you have some firewall issues.

you can find my elasticsearch window i.e overview window and browse window.

from these windows i think you can get what i am doing.  
i just create new indexes with type and their id simply .  
before this i din't created any cluster or any node e.t.c. ,from my knowledge i have not created,but from ES site i came to know that cluster will be created bydefault and node aswell,but i have not given any cluster name or any specific thing or nodes.

i think i am not making any complication about this.

but to be frank..i am moving here and there like a child to know what is happening.

There is something wrong with your set-up

How many ES node s you have ?  
On which IP addresses are ES hosts listening ?

I understood you have 2 hosts , but it seems you have only one on your local machine .

This is the code (a bit modified) I am using at the moment

public void connectES() {  
Set hosts = new HashSet();  
hosts.add("[host1.mydomain.com](http://host1.mydomain.com)");  
hosts.add("[host2.host1.mydomain.com](http://host2.host1.mydomain.com)"); // Make sure this resolvs to proper IP address  
Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name", "vesseltrackerES").build();

TransportClient transportClient = new TransportClient(settings);  
for (String host : this.hosts) {  
transportClient = transportClient.addTransportAddress(new InetSocketTransportAddress(host, 9300));  
}

System.out.print("Connected to nodes : ");  
for (DiscoveryNode node : transportClient.connectedNodes()) {  
System.out.print(node.getHostName() + " , ");  
}  
System.out.println("");

this.client = (Client) transportClient;  
}

Make sure that 192.168.1.100/101 is the right IP address of the host1/host2

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);

```

}

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.

If you did not change the cluster name , it is the default one : elasticsearch

Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name", "elasticsearch").build();

Works fine for me.

Either your elasticsearch is not running locally, or your cluster name is not vesseltrackerES or you have some firewall issues.

There is something wrong with your set-up

How many ES node s you have ?  
On which IP addresses are ES hosts listening ?

I understood you have 2 hosts , but it seems you have only one on your local machine .

This is the code (a bit modified) I am using at the moment

public void connectES() {  
Set hosts = new HashSet();  
hosts.add("[host1.mydomain.com](http://host1.mydomain.com)");  
hosts.add("[host2.host1.mydomain.com](http://host2.host1.mydomain.com)"); // Make sure this resolvs to proper IP address  
Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name", "vesseltrackerES").build();

TransportClient transportClient = new TransportClient(settings);  
for (String host : this.hosts) {  
transportClient = transportClient.addTransportAddress(new InetSocketTransportAddress(host, 9300));  
}

System.out.print("Connected to nodes : ");  
for (DiscoveryNode node : transportClient.connectedNodes()) {  
System.out.print(node.getHostName() + " , ");  
}  
System.out.println("");

this.client = (Client) transportClient;  
}

Make sure that 192.168.1.100/101 is the right IP address of the host1/host2

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);

```

}

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.

How are you running the code? If it is a java app have you specified all  
the jar in the path?

yes david,i have already done wat you have suggested me.

private static void buildClient() {  
Settings settings =  
ImmutableSettings.settingsBuilder().put("cluster.name",  
"elasticsearch").build();  
client = new TransportClient(settings)  
.addTransportAddress(new  
InetSocketTransportAddress("localhost", 9300));  
}

```
public static void main(String[] args) {

    buildClient();

    SearchResponse response = 

```

client.prepareSearch().execute().actionGet();  
System.out.println("response.getHits().totalHits() = " +  
response.getHits().totalHits());  
}

but when i execute i am getting o/p like :

Mar 24, 2014 2:29:06 PM org.elasticsearch.client.transport  
WARNING: [Microchip] failed to get node info for

Q)Actually why i am putting port 9200?

Ans: my elasticsearch url index is with port 9200,so i am trying to put  
9200 in the place of 9300,but you initiated me to 9300.

is there any reason for 9300?
