ES Cluster Name in different AWS Data Center

Hi,

I have a ES Cluster with name "log_cluster" in Singapore AWS DC.
Now I want to bring new ES Cluster on Ireland DC and this should run independent of Singapore DC.

IF I give same ES cluster name "log_cluster" to Ireland DC will it form a group with Singapore DC ? (Assume both DC are reachable)

Do I need to give different cluster name to work ES Cluster independently?

Appreciate your help.

Thanks
Naresh.

What version are you on?

1.X it may, 2.X it won't.

Thanks for the quick reply.

I am on version 2.1.0

Does it mean same cluster name in different DC wont form a group?

Not unless you list the other clusters nodes in unicasts hosts.

But you are probably better off using a different cluster name, make it region specific.

Thanks a lot.
