Christophe Jolif commented on FLINK-8101: ----------------------------------------- It seems Elasticsearch is slowly moving away from the binary-basedĀ TransportClient in favor of HTTP-based clients. SeeĀ https://www.elastic.co/guide/en/elasticsearch/client/java-rest/5.6/index.html In addition to being sure the Elasticsearch direction is followed, this also have the advantage of being able to work through firewalls and such which is pretty common today with hosted versions of Elasticsearch. Is the intend for this support to leverage the new clients or not? > Elasticsearch 6.x support > ------------------------- > > Key: FLINK-8101 > URL: https://issues.apache.org/jira/browse/FLINK-8101 > Project: Flink > Issue Type: New Feature > Components: ElasticSearch Connector > Affects Versions: 1.4.0 > Reporter: Hai Zhou UTC+8 > Assignee: Hai Zhou UTC+8 > Priority: Major > Fix For: 1.5.0 > > > Recently, elasticsearch 6.0.0 was released: > https://www.elastic.co/blog/elasticsearch-6-0-0-released > The minimum version of ES6 compatible Elasticsearch Java Client is 5.6.0 -- This message was sent by Atlassian JIRA (v7.6.3#76005)
