Etienne Chauchot commented on BEAM-2347:
----------------------------------------
[~sisk] actually, the whole ES IO is only compatible with ES 2.x (this
incompatibility is not related to the client version), there is an open ticket
(https://issues.apache.org/jira/browse/BEAM-1637) about providing support for
ES 5.x. We use ES REST client because REST protocol allows decoupling ES client
and ES server. This REST client appeared in ES v5. There is no relation with
the java version. I will resume working on ES v5 support and I'll update the IT
when the IO supports both ES v2.x and ES v5.x
> Elasticsearch IO - test ES 5?

> Key: BEAM-2347
> URL: https://issues.apache.org/jira/browse/BEAM-2347
> Project: Beam
> Issue Type: Bug
> Components: sdk-java-extensions
> Reporter: Stephen Sisk
> Assignee: Jean-Baptiste Onofré
>
> Currently, the ES IO transform uses the v5 REST API client, but the
> integration tests only work against ES 2x
> I'm guessing this is because the ES 5x java client only supports java 8 -
> https://discuss.elastic.co/t/elasticsearch-5-0-java-api-5-0-on-jdk-7/68222
> I don't know ES particularly well, but I'm guessing it'd be nice to make the
> ITs work against ES 5 as well as ES 2. It seems like there are two options
> for this:
> 1. Make the ITs java-8 only (as is done in HadoopInputFormat ITs)
> 2. Switch the ITs to use the ES5 REST API client, which supports java 7.
> [~echauchot] am I missing anything here?
