Hi,
I want to attach one more node to running cluster.
Can i do it directly by starting one more instance with pre-requisite setting in ES config?
What more I need to do apart from cluster.name ?
What is impact on existing indexes?
br,
Sunil

Not sure I understood the question.
What more I need to do apart from cluster.name ?
Set the discovery unicast list of nodes that are already running so they can discover each others.
What is impact on existing indexes?
Allocation of missing replicas if any and rebalancing of shards if needed...
I mean, I will start ES with same cluster.name on another server in the same network.
discovery.zen.ping.unicast.hosts: ["ip-master","ip-data-node-1","ip-data-node-2"]
is this setting you are talking about?
Is re-balancing of shards required? How to do that?

Yes

It's automatic. Don't worry about that.
Hi,
Thanks.
Does it slows down the cluster when additional node joined?
I mean, may be because of re-balancing?

Not that much. Nothing you can notice unless you are already under a heavy load.
IIRC recovery process use at most 20mb/s bandwidth.
