Martijn Visser commented on FLINK-29785:
----------------------------------------

This isn't possible, because that newer version of the Elasticsearch connector is released under a new license that's not compatible with the Apache License. See FLINK-26088

> `elasticsearch-7` connector uses ElasticSearch `7.10.2` version.
> [https://github.com/apache/flink-connector-elasticsearch/blob/main/flink-connector-elasticsearch7/pom.xml#L39]
>  
> When ElasticSearch server side is `8.X.X` then, `elasticsearch-7` connector does not work. For Example for ElasticSearch `8.2.2` version on the server side, the minimum required version on the `elasticsearch-7` Flink connector side is `"minimum_wire_compatibility_version" : "7.17.0"`.
> As of today `elasticsearch-8` does not exist yet. [ Add Elasticsearch 8.0 support Jira ticket |https://issues.apache.org/jira/browse/FLINK-26088 ] .
> With this intermediare step - upgrading `elasticsearch-7` connector `elasticsearch.version` to 7.17.0 can help Flink users still ingest into ElasticSearch which has `8.X.X` version deployed on the server side.
