CXF : Elasticsearch Java API - spring

Question

When using Elasticsearh Java API inside Servlet in Tomcat, getting "org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are available"
I am trying to create a simple REST API using cxf.
It will do following work -
will read some records from Elasticsearch cluster(using https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/index.html).
Return the return the result as Json.
When I heat the url = "http://localhost:8080/aee-services/sequence/?txID=5f64f331-63c9-485d-9018-6872b1cf5f91"
I am getting this
/sequence : txId = 5f64f331-63c9-485d-9018-6872b1cf5f91

Please correct me where I am wrong
Can we use Elasticsearch Java API inside Servlen Container?
Note when I am testing using J4Unit test case it is working fine.

Answer 1

Plz ensure that the cluster name you have provided in the transport client (onap-cluster) matches with the actual cluster name.
Also any reason for adding the same ip (10.247.83.8) twice?
