Log Context

Log “undefined host_type [{}]. Please check your settings.” classname is AzureUnicastHostsProvider.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

                             logger.trace("no public ip provided. ignoring [{}]..."; instance.getInstanceName());
                        }
                        break;
                    default:
                        // This could never happen!
                        logger.warn("undefined host_type [{}]. Please check your settings."; hostType);
                        return cachedDiscoNodes;
                }

                if (networkAddress == null) {
                    // We have a bad parameter here or not enough information from azure
