Hi ! I created a script to automate the installation of elasticsearch 5. It works fine. But now I have a problem with elasticsearch: I can't have the cluster health and I have several errors. first the elasticsearch config: ``` network.bind_host: 0.0.0.0 network.publish_host: 10.136.1.123 (the ip of the host) discovery.zen.minimum_master_nodes: 2 node.name: Aquaman node.master: true node.data: true discovery.zen.ping.unicast.hosts: ["liprd071.adellego.com", "liprd073.adellego.com", "liprd074.adellego.com"] (not the same for all the node) ``` The thing is when I put curl -XGET 'localhost:9200/\_cluster/health?pretty', I've got nothing (It doesn't stop) And this is a part of the log: [2016-11-16T14:23:29,768][ERROR][o.e.g.GatewayService] [Superman] unexpected failure during [local-gateway-elected-state] org.elasticsearch.cluster.NotMasterException: no longer master. source: [local-gateway-elected-state] [2016-11-16T14:23:29,768][INFO][o.e.g.GatewayService] [Superman] metadata state not restored, reason: failed to updated cluster state [2016-11-16T14:23:32,763][INFO][o.e.c.s.ClusterService] [Superman] new\_master {Superman}{EWHY0pBdRS6jEyTmE\_HJdw}{xybavZhcR0yZ9wDpjHUVTQ}{10.136.1.115}{10.136.1.115:9300}, reason: zen-disco-elected-as-master ([1] nodes joined)[{l1BSU3u}{l1BSU3uLRwiA4Jelt-LKYw}{vC6v6nYcQTiwONQOSkoz8w}{127.0.0.1}{127.0.0.1:9300}] [2016-11-16T14:24:02,763][WARN][o.e.d.z.p.PublishClusterStateAction] [Superman] timed out waiting for all nodes to process published state [21] (timeout [30s], pending nodes: [{l1BSU3u}{l1BSU3uLRwiA4Jelt-LKYw}{vC6v6nYcQTiwONQOSkoz8w}{127.0.0.1}{127.0.0.1:9300}]) [2016-11-16T14:24:02,764][WARN][o.e.c.s.ClusterService] [Superman] cluster state update task [zen-disco-elected-as-master ([1] nodes joined)[{l1BSU3u}{l1BSU3uLRwiA4Jelt-LKYw}{vC6v6nYcQTiwONQOSkoz8w}{127.0.0.1}{127.0.0.1:9300}]] took [30s] above the warn threshold of 30s [2016-11-16T14:24:02,764][WARN][o.e.d.z.ZenDiscovery] [Superman] discovered [{Superman}{EWHY0pBdRS6jEyTmE\_HJdw}{xybavZhcR0yZ9wDpjHUVTQ}{10.136.1.115}{10.136.1.115:9300}] which is also master but with an older cluster\_state, telling [{Superman}{EWHY0pBdRS6jEyTmE\_HJdw}{xybavZhcR0yZ9wDpjHUVTQ}{10.136.1.115}{10.136.1.115:9300}] to rejoin the cluster ([via a new cluster state]) [2016-11-16T14:24:02,765][WARN][o.e.d.z.ZenDiscovery] [Superman] received a request to rejoin the cluster from [EWHY0pBdRS6jEyTmE\_HJdw], current nodes: {{Superman}{EWHY0pBdRS6jEyTmE\_HJdw}{xybavZhcR0yZ9wDpjHUVTQ}{10.136.1.115}{10.136.1.115:9300},{Aquaman}{fwYilkxgQgWSMsk673R6ww}{YVly9M3GTCaKNwTgugxV8A}{10.136.1.123}{10.136.1.123:9300},{l1BSU3u}{l1BSU3uLRwiA4Jelt-LKYw}{vC6v6nYcQTiwONQOSkoz8w}{127.0.0.1}{127.0.0.1:9300},} [2016-11-16T14:24:02,773][ERROR][o.e.g.GatewayService] [Superman] unexpected failure during [local-gateway-elected-state] org.elasticsearch.cluster.NotMasterException: no longer master. source: [local-gateway-elected-state] [2016-11-16T14:24:02,773][INFO][o.e.g.GatewayService] [Superman] metadata state not restored, reason: failed to updated cluster state [2016-11-16T14:24:05,890][INFO][o.e.c.s.ClusterService] [Superman] new\_master {Superman}{EWHY0pBdRS6jEyTmE\_HJdw}{xybavZhcR0yZ9wDpjHUVTQ}{10.136.1.115}{10.136.1.115:9300}, reason: zen-disco-elected-as-master ([1] nodes joined)[{Aquaman}{fwYilkxgQgWSMsk673R6ww}{YVly9M3GTCaKNwTgugxV8A}{10.136.1.123}{10.136.1.123:9300}] Superman is the first node and Aquaman the second. What have I done wrong ? Thank you ! ---

You should read : [https://www.elastic.co/guide/en/elasticsearch/reference/5.0/modules-discovery-zen.html#master-election](https://www.elastic.co/guide/en/elasticsearch/reference/5.0/modules-discovery-zen.html#master-election) ``` This setting must be set to a quorum of your master eligible nodes. It is recommended to avoid having only two master eligible nodes, since a quorum of two is two. Therefore, a loss of either master eligible node will result in an inoperable cluster. ``` ---
