I have setup a 5 node cluster and each node has the following in the YML file  
what's the implication ? what is the right way to setup a cluster ? I think there is some master slave roles involved and I am not sure I understand the role of zen.min.master\_nodes parameter.

> cluster.name: ftes  
> node.name: hadoop1  
> node.master: true  
> node.data: true  
> path.data: /u01/elastic/data  
> path.logs: /u01/elastic/logs  
> path.repo: /u01/elastic/es\_backup  
> network.host: hadoop1  
> discovery.zen.minimum\_master\_nodes: 3  
> bootstrap.system\_call\_filter: false  
> #discovery.zen.ping.unicast.hosts: [“hadoop1”,“hadoop2”,“hadoop3”,“hadoop4”,“hadoop5”]  
> discovery.zen.ping.unicast.hosts: ["hadoop1","hadoop2","hadoop3","hadoop4","hadoop5"]
