I have following setup for 3 node cluster , all being master eligible as recommended by few folks in this discussion.

```
node.name : node1 [node2, node3]
node.master: true
node.data: true
```

My questions, don't i need any client node ? like node.master : false and node.data : false  
if not how will the routing work? which node will receive all my read requests through java API?

thanks  
Sam

No it's not needed.

The node which the transport client will connect to is the one you defined in the transport client. That could be the 3 nodes.

Thanks a lot, so in my java TransportClient , i need to add all the 3 nodes. and it does the routing itself.  
by the way i am using 5.4.0 version , don't i need any ingest node?

No unless you use the ingest API.
