Elastic Stack Logstash

Hello,

I am trying to use jdbc input plugin using logstash so that i can fetch data from sql database and create the index.
But when i am running config file for logstash. It is showing me below error:

[2020-01-22T10:04:27,133][WARN ][logstash.outputs.elasticsearch][main] Attempted to resurrect connection to dead ES instance,
but got an error. {:url=>"http://127.0.0.1:9200/", :error_type=>LogStash::Outputs::Elasticsearch::HttpClient::Pool::HostUnreachableError, :error=>"Elasticsearch Unreachable: [http://127.0.0.1:9200/][Manticore::SocketException] Connection refused: connect"}

I have clustering enable with 3 nodes.
Can anyone guide me on the same?

Reagrds,
Priyanka
