I would like to dynamically set discovery.zen.ping.multicast.enabled and discovery.zen.ping.unicast.hosts -- is this possible? I've been looking for a REST API call that I can make from my Go program. I have a situation where I can't use multicast (running on GCE) and the cloud-gce plug-in [https://github.com/elastic/elasticsearch-cloud-gce](https://github.com/elastic/elasticsearch-cloud-gce) won't work for my scenario. Thank you kindly. Cheers, Satnam -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

This is not a dynamic setting, it needs to be defined in your config file and ES needs to be restarted to read it.
