---------------------------------------
Summary: Upgrade Flink Elasticsearch-7 connector
elasticsearch.version to 7.17.0
Key: FLINK-29785
URL: https://issues.apache.org/jira/browse/FLINK-29785
Project: Flink
Issue Type: Improvement
Components: Connectors / ElasticSearch
Reporter: Elkhan Dadashov
`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.
