Hello. I'm new to elasticsearch and I'm trying to change the configuration file.  
So I uncommented cluster.name and node.name lines and renamed them, which work fine after waiting for a few seconds. However, I tried adding the following lines after node.name and it stops working (connection refused):

> ```
> node.master: false
> node.data: true
> index.number_of_shards: 5
> index.number_of_replicas: 1
> network.host: 0.0.0.0
> transport.tcp.port: 9301
> transport.tcp.compress: true
> http.port: 9201
> http.enabled: true
> discovery.zen.minimum_master_nodes: 1
> discovery.zen.ping.timeout: 10s
> discovery.zen.ping.multicast.enabled: false
> discovery.zen.ping.unicast.hosts: ["127.0.0.1:9300"]
> 
> ```

Any suggestions?
