I believe that the host names must be comma-separated and no quotes or other punctuation should be present. The config within the environment variable or java -D (system properties) is YAML-like, not JSON. No blanks between the names, for example:
export ES_HOSTS=host1,host2,host3 When configuring Unicast, here are the java -D options I use in my own custom Elasticsearch start-up / shutdown / status script: -Des.discovery.zen.ping.multicast.enabled=false -Des.discovery.zen.ping.unicast.hosts=host1,host2,host3 -Des.discovery.zen.minimum_master_nodes=2 Brian -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
