RestElasticSearchClient - Unable to determine Elasticsearch server version. Default to FIVE

#1272

Hello,

JanusGraph doesn't work with Elasticsearch version 6.

Here is the connection:

JanusGraph g = JanusGraphFactory.build().

set("storage.backend", "cassandra").

set("storage.hostname", "10.10.10.21").

set("storage.username", "cassandra").

set("storage.password", "cassandra").

set("index.search.backend", "elasticsearch").

set("index.search.hostname", "10.10.10.21").

open();

Here are logs:

It's not actually connecting hence "Connection refused". Check your IP, port configuration. Verify Elasticsearch is listening there.
