Hi, I have set up ES server in AWS, and it seems to be working fine. I am trying to connect programmatically to this server from my java client, by creating a node (java application is running outside the cloud). However, I am getting binding error : [https://gist.github.com/1376202](https://gist.github.com/1376202) It this possible? Please let me know if I am doing something wrong. My Java node object is created with following attributes: cluster.name : network.host : (In server, I have configured this name with private IP of server) discovery.type : ec2 cloud.account : cloud.key: ---

Thanks, Alex. I have tried this, but I get the following error: : Invocation of init method failed; nested exception is org.elasticsearch.transport.BindTransportException: Failed to bind to [9300-9400] I have opened all necessary ports in EC2. ---

Probably something is already bound to these ports. Check something like lsof -i Alexandr Vasilenko 2011/11/18 achaayan [felixmd@gmail.com](mailto:felixmd@gmail.com) > Thanks, Alex.

If you connect to your cluster on AWS from outside AWS, use transport client, with sniff disabled (its the default).

Thanks. I have tried this, but I get an exception: org.elasticsearch.transport.RemoteTransportException: Failed to deserialize response of type [org.elasticsearch.action.admin.cluster.node.info.NodesInfoResponse] Caused by: org.elasticsearch.transport.TransportSerializationException: Failed to deserialize response of type [org.elasticsearch.action.admin.cluster.node.info.NodesInfoResponse] at org.elasticsearch.transport.netty.MessageChannelHandler.handleResponse(MessageChannelHandler.java: 126) at org.elasticsearch.transport.netty.MessageChannelHandler.messageReceived(MessageChannelHandler.java: 103) at org.elasticsearch.common.netty.channel.SimpleChannelUpstreamHandler.handleUpstream(SimpleChannelUpstreamHandler.java: 80) It would be great if you could provide me some directions.

Answered on another thread you opened, I think you use different versions of elasticsearch.

Thanks, Shay - changing client jar version fixed this problem. Both threads described same issues, but on different scenarios.
