I have three nodes setup running oss-7.8.1 on CentOS 7 with SELinux Disabled

I'm just trying to do a very basic initial setup as this is my first time playing with it. I have been reading different walkthroughs as well as documentation and am not sure what I'm missing.

I setup 3 nodes identically with puppet and made them so they could each be master eligible. When the services start I curl the API to see the cluster status and they each only show 1 node in the cluster with themselves as the master.

Here is my config... The servers use DNS & I've tested resolution of the host names. I've changed he hostnames for purpose of sharing online.

```auto
### MANAGED BY PUPPET ###
---
cluster.initial_master_nodes:
- elastic-host01
- elastic-host02
- elastic-host03
cluster.name: elasticsearch-development
discovery.seed_hosts:
- elastic-host01
- elastic-host02
- elastic-host03
network.host: 0.0.0.0
node.master: true
node.data: true
node.name: elastic-host01-elastic-host01
path.data: "/var/lib/elasticsearch/elastic-host01"
path.logs: "/var/log/elasticsearch/elastic-host01"`

```

Same config on each host

Here is curl output from one of my hosts

```auto
curl -XGET 'http://localhost:9200/_cluster/state?pretty'
{
  "cluster_name" : "elasticsearch-development",
  "cluster_uuid" : "TNNUNFFZQfaFNqbMjyJw2g",

      ],
      "last_accepted_config" : [

      ],

  },
  "routing_nodes" : {
    "unassigned" : [],
    "nodes" : {
      "1K7aq5XdRf6-P30-Veo7Qg" : []
    }
  }
}

```

```auto
curl -XGET 'http://localhost:9200/_cat/nodes?'
196.158.5.130 9 81 0 0.00 0.01 0.05 dimr * elastic-host01-elastic-host01'

```

Any help would be greatly appreciated.. I feel it's really silly. Thank you!

You must have some data in your nodes' data paths from a previous config in which they were the only node. Wipe the data path and you should be good to go. Possibly [this note in the docs](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery-bootstrap-cluster.html#modules-discovery-bootstrap-cluster-joining) is what you're looking for.

BTW don't put your logs in your data path.

Thank you for that info! I will try that out in a moment. I must have read through that page 50 times. I don't know how I missed the line I needed. Thanks again and I'll comment back if it solves my issue.
