Hi Currently, I am currently configuration a 4 Node cluster with 1 Master and 3 data Nodes within a Cluster When i do a curl http://:9200/\_cat/nodes?v I am getting the following `{"error":{"root_cause":[{"type":"master_not_discovered_exception","reason":null}],"type":"master_not_discovered_exception","reason":null},"status":503}root@ip-10-7:/var/log/elasticsearch#` elasticsearch.yml File: ``` # Use a descriptive name for your cluster: # cluster.name: RMDEV # # ------------------------------------ Node ------------------------------------ # # Use a descriptive name for the node: # node.name: Master node.data: False node.master: true # # Add custom attributes to the node: # #node.attr.rack: r1 # # ----------------------------------- Paths ------------------------------------ # # Path to directory where to store the data (separate multiple locations by comma): # path.data: /var/lib/elasticsearch # # Path to log files: # path.logs: /var/log/elasticsearch # # ----------------------------------- Memory ----------------------------------- # # Lock the memory on startup: # #bootstrap.memory_lock: true # # Make sure that the heap size is set to about half the memory available # on the system and that the owner of the process is allowed to use this # ---------------------------------- Network ----------------------------------- # # Set the bind address to a specific IP (IPv4 or IPv6): # network.host: [_local_,_site_] # # Set a custom port for HTTP: # http.port: 9200 # # For more information, consult the network module documentation. # # --------------------------------- Discovery ---------------------------------- # # Pass an initial list of hosts to perform discovery when this node is started: #The default list of hosts is ["127.0.0.1", "[::1]"] # discovery.seed_hosts: [":9200"] # # Bootstrap the cluster using an initial set of master-eligible nodes: # cluster.initial_master_nodes: [":9200"] # # For more information, consult the discovery and cluster formation module documentation. # # ---------------------------------- Gateway ----------------------------------- # # Block initial recovery after a full cluster restart until N nodes are started: # #gateway.recover_after_nodes: 3 ``` Node Configuration File: ``` # Use a descriptive name for your cluster: # cluster.name: RMDEV # # ------------------------------------ Node ------------------------------------ # # Use a descriptive name for the node: # node.name: node-3 node.data: true node:master: False # # Add custom attributes to the node: # #node.attr.rack: r1 # # ----------------------------------- Paths ------------------------------------ # # Path to directory where to store the data (separate multiple locations by comma): # path.data: /var/lib/elasticsearch # # Path to log files: # path.logs: /var/log/elasticsearch # # ----------------------------------- # ---------------------------------- Network ----------------------------------- # # Set the bind address to a specific IP (IPv4 or IPv6): # network.host: [_local_,_site_] # # Set a custom port for HTTP: # http.port: 9200 # # For more information, consult the network module documentation. # # --------------------------------- Discovery ---------------------------------- # # Pass an initial list of hosts to perform discovery when this node is started: # The default list of hosts is ["127.0.0.1", "[::1]"] # discovery.seed_hosts: [":9200"] # # Bootstrap the cluster using an initial set of master-eligible nodes: # cluster.initial_master_nodes: [":9200"] # # For more information, consult the discovery and cluster formation module documentation. # # ---------------------------------- Gateway ----------------------------------- # # Block initial recovery after a full cluster restart until N nodes are started: # #gateway.recover_after_nodes: 3 # # For more information, consult the gateway module documentation. # # ---------------------------------- Various ------------------ ``` ---

error says it can't connect to host. your config file has node.name=master is this valid systemname? your network.host entry says [_local_,_site_] I think it should be ip address of your master server and your curl command should be something like curl -Xget http://:9200/\_cluster/health?pretty ---

Hi, this _local_,_site_ binds both local 127.0.0.1 and the private IP address. > ### Special values for `network.host` [edit](https://github.com/elastic/elasticsearch/edit/7.0/docs/reference/modules/network.asciidoc) > > The following special values may be passed to `network.host` : > > | `_[networkInterface]_` | Addresses of a network interface, for example `_en0_` . | > | --- | --- | > | `_local_` | Any loopback addresses on the system, for example `127.0.0.1` . | > | `_site_` | Any site-local addresses on the system, for example `192.168.0.1` . | > | `_global_` | Any globally-scoped addresses on the system, for example `8.8.8.8` . | ---

Can you share the log messages from this node? They should be describing why the master is not being discovered in more detail. ---
