Error during elasticsearch cluster setup

Elastic Stack Elasticsearch
1

I am trying to setup an elasticsearch cluster with 3 nodes. I am using es version 5.1.2.
The node details are as follows:
node1: 10.248.9.42
node2: 10.242.235.167
node3: 10.88.28.33

The node1 configuration is as follows:

cluster.name: my-cluster-1
node.name: node1
network.host: 0.0.0.0
transport.host: 10.248.9.42
transport.tcp.port: 9300
http.port: 9200
indices.query.bool.max_clause_count: 4096

discovery.zen.minimum_master_nodes: 2
discovery.zen.ping.unicast.hosts: ["10.248.9.42", "10.242.235.167", "10.88.28.33"]

When I start elasticsearch on node1, it can start successfully.

The node2 configuration is as follows:
cluster.name: my-cluster-1
node.name: node2
network.host: 0.0.0.0
transport.host: 10.242.235.167
transport.tcp.port: 9300
http.port: 9200
indices.query.bool.max_clause_count: 4096

discovery.zen.minimum_master_nodes: 2
discovery.zen.ping.unicast.hosts: ["10.248.9.42", "10.242.235.167", "10.88.28.33"]

When I try starting elasticsearch on node2, I am getting below error.
What is going wrong here?

P.S. I have verified that port 9300 is not in use by any other process in node2.

Hi,

In all your configurations, remove "transport.host" entries,

and just set "network.host":

network.host: ["10.242.235.167", "127.0.0.1"] # add or remove entries you need to bind

bye,
Xavier

May I know why this change is necessary and what is wrong with my configuration?
As I mentioned, elasticsearch is running fine in node1 with above configuration.

"transport.host" overwrite "network.host" setting.

Does your node2 have a special connection ?

Cannot assign requested address bind0(Native Method) ~[?:1.8.0_121]

Thanks. I did not get what you mean by-
Does your node2 have a special connection?
Please elaborate.
