I am starting to implement elastic search in my project. The project is J2EE application deployed on Weblogic Clustered environment. Which means my java classes would be present at different locations/nodes in a cluster. If I use Elastic search Java api to put/get data , will it look only for the ES nodes on that particular node or throughout my Weblogic Cluster setup. If only local node , then what should I do to make sure all the logs from my Applications Server nodes are in sync. Should I go for one single node at a location and use that location in all my classes to put/get data? If yes, then a small code snippet would be helpful. Regards ---

You can imagine launching an elasticsearch node local to every single weblogic instance but with: ```auto node.data: false node.master: false ``` in `elasticsearch.yml` file. You will have a client node. Then in your application, just use a [TransportClient](https://www.elastic.co/guide/en/elasticsearch/client/java-api/master/transport-client.html) which connects locally to the local elasticsearch node (basically to `127.0.0.1:9300`). All client nodes will write/read to/from your elasticsearch cluster which will run on its own on other machines. Make sense? ---

Yes makes sense David. Just one thing : You say- "in elasticsearch.yml file. You will have a client node." I understand, I will have to set the IP address and port of ES data cluster. Which property to be set in yaml to do this? Forgive my ignorance, I am just a beginner in the area. Regards ---

I meant that you download elasticsearch, unzip, then modify the existing `config/elasticsearch.yml` file and set in it: ```auto node.data: false node.master: false # And probably: cluster.name: yourclustername network.host: _eth0_ discovery.zen.ping.unicast.hosts: ["x.x.x.x:9300", "x.x.x.y:9300", "x.x.x.z:9300"] ``` Where `x.x.x.*` are the IP of your cluster. Then launch your local node with `bin/elasticsearch`. It will join the cluster (which is running at `x.x.x.*`). Then in your java code, use the transport client as I described. ---

Got iT.. Will try the same Thanks 👍 ---
