It explains it in the error - `The setting`host`in plugin`elasticsearch`is obsolete and is no longer available. Please use the 'hosts' setting instead.`

Check the docs - [https://www.elastic.co/guide/en/logstash/current/plugins-outputs-elasticsearch.html#plugins-outputs-elasticsearch-hosts](https://www.elastic.co/guide/en/logstash/current/plugins-outputs-elasticsearch.html#plugins-outputs-elasticsearch-hosts)
