Leonid Ilyevsky updated FLINK-13886:
------------------------------------
Affects Version/s: 1.8.0
1.8.1
> Need to develop flink-connector-elasticsearch7
> ----------------------------------------------
>
> Key: FLINK-13886
> URL: https://issues.apache.org/jira/browse/FLINK-13886
> Project: Flink
> Issue Type: Improvement
> Components: Connectors / ElasticSearch
> Affects Versions: 1.8.0, 1.8.1, 1.9.0
> Reporter: Leonid Ilyevsky
> Priority: Major
>
> The flink-connector-elasticsearch6 is not compatible with Elasticsearch 7.x.
> If you try to use elasticsearch-rest-high-level-client version 7.x with
> flink-connector-elasticsearch6 instead of 6.x, you get fatal exception:
> {{java.lang.NoSuchMethodError:
> org.elasticsearch.client.RestHighLevelClient.ping([Lorg/apache/http/Header;)Z}}
> {{ at
> org.apache.flink.streaming.connectors.elasticsearch6.Elasticsearch6ApiCallBridge.createClient(Elasticsearch6ApiCallBridge.java:81)}}
> {{......}}
>
> Some changes in Elastic 7.x make it necessary to use compatible client
> library, specifically the deprecated 'type' element in the document
> structure.
> With 6.x client library the 'type' element is mandatory, so it has to be in
> each document, but then the 7.x sever will send back a warning for every
> single document. Workaround: suppress those warnings in the logging
> configuration.
