It is possible to run elasticsearch version 5.x in Apache Flink 1.2.0? I cannot upgrade my Flink to 1.3 because I need the 1.2.0 version to run kafka.
by what it is said in this link : https://ci.apache.org/projects/flink/flink-docs-release-1.3/dev/connectors/elasticsearch.html
flink-connector-elasticsearch5_2.10 (Supported since) 1.2.0 (Elasticsearch version) 5.x
This connector should work (since that my Flink version it is 1.2.0), but when I run it it doesn't work.
Do I need to install Elasticsearch 2.x or there is some other way to make it work?
Thanks.
