I'm using drupal-7.53 with elasticsearch_connector (7.x-1.0-alpha9):

# drush -r . -l alexustest pm-list | grep Elasticsearch

While adding "Elasticsearch Clusters", I'm getting following message:

Cannot connect to the cluster!

and even though I enabled "Elasticsearch Connector Easy Install", I couldn't find anything relevant to this module (where/how to do easy install)

Please advice.

Thank you in advance!

@alexus,

You are using version 5.0 of Elasticsearch and this version is not supported by 7.x module yet.
There is a patch for Elasticsearch 2.x server version but it is still not fully usable. See the module description page with versioning info for more details about this.
We will start work on 5.x maybe the beginning of next year.

Related issues: +#2842993: Elasticsearch 5.x integration with Drupal 7.x-5.x

@alexus,

Please follow this issue for the integration with 5.x Elasticsearch server - https://www.drupal.org/node/2842993.

@Drupali, can you please go to you Drupal status page and see if everything with the Elasticsearch client is OK?
This error should be connected with something on HTTP connection to the Elasticsearch.

I tried again and even though I'm still getting an error:

@skek does the connector still work when the cluster health is at yellow?

Also, I noticed the error goes away when I enable Elasticsearch Connector Devel module. Is it intentional?
