creating transport client for elastic search throws unknown host exception

Question

Client client = TransportClient.builder().build()
                .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("mon1"),9300));

I am using the above code snippet to create a transport client for my elastic search using java API, but it throws exception for the method InetAddress.getByName() . Says Unknown Host Exception . Do I need to create some configuration file for it? If yes, please provide details.

Note :- I am not using a elastic search cluster on my local machine.

Answer 1

InetAddress.getByName throws an unhandled exception "host not found"

Put the entire code in try catch block, It will work. :-)

Note:- Elasticsearch.yml file is needed. Put it in your resources folder if you are using java API
