My kafka cluster ip address is : 192.168.1.9 , 192.168.1.10
However if i'm installing elasticsearch on same machine as kafka and changing connection.url=http://localhost:9200 i'm able to view index created without any docs in it
Note that this document is quite old. One thing that has changed in Elasticsearch is that document types have been deprecated and removed so it is possible that type.name=log is causing problems if you are using a recent version of Elasticsearch. Try removing this or change it to _doc. I am not familiar with this connector and it is not supported here, so you may need to reach out to the maintainers or the Kafka community for guidance and compatibility information.
