I'm wondering if anyone has experience configuring a Kubernetes cluster using the Elasticsearch for Hadoop library. I'm running into issues with the node discovery timing out when trying to write from spark to elasticsearch. I have Elasticsearch up and running thanks to the elasticsearch-cloud-kubernetes plugin for ES, which handles discovery, but I'm not sure how best to configure elasticsearch-hadoop to be aware of the nodes (pods) within the kubernetes cluster. I've tried setting spark.es.nodes to a es-client service, but that doesn't seem to work. I'm also aware that I could enable es.nodes.wan.only, but as noted in the documentation, this would severely impact performance, which defeats the purpose of having them running on the same cluster. Any help would be appreciated.
