Hi, Can anyone tell me why my Elasticsearch Transport Client does not complain when not finding a cluster ? Code here : [https://github.com/YannBrrd/json-import/blob/master/src/main/java/org/yaba/curbside/ESInjector.java#L92](https://github.com/YannBrrd/json-import/blob/master/src/main/java/org/yaba/curbside/ESInjector.java#L92) Thanks.

Is it the same with "client.transport.sniff" set to false? Jörg -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Yes. In the end Shay told me to use conectedNodes from the client API.
