I'm trying to set up a simple master-1 node with data-1 and data-2 but when I look at the log [I get this error](http://puu.sh/FZQwv/3f31394ba7.png). All nodes are fresh CentOS 7 machine that can ping each other. For all the cluster I've set:

```auto
    cluster.name: playground
    node.name: <their name master-1/data-1/data-2>
    network.host: [_local_,_site_]
    http.port: 9200 
    discovery.seed_hosts: ["<internal IP of master>"]
    cluster.initial_master_nodes: ["master-1"]
    (at the end):
    node.master: (only true for master-1)
    node.data: true
    node.ingest: false
    node.ml: false

```

Does anyone knows what's going on? Thanks ahead!
