Is this the case the even if discovery.zen.ping.multicast.enabled is false?

Yes. Just launch the new node and set its unicast values to other running nodes.
It will connect to the cluster and the cluster will add him as a new node.

You don't have to modify existing settings, although you should do it to have 
updated settings in case of restart.

Hi
I am having an elasticsearch cluster. I am using the unicast to discover nodes. 
Can I add nodes to list dynamically without restarting the cluster? 
I tried to do this with the prepareUpdateSettings but i got "ignoring transient 
setting [discovery.zen.ping.unicast.hosts], not dynamically updateable".
Is there any other way to do this without restarting the cluster.

I am not going for multicast because i don't want rouge nodes to join my 
cluster. I can go for it if i can, in anyway, limit what all nodes join the 
cluster, other than the cluster name.
Are there any ways to do this.

Thanks 
Hari
