Does elasticsearch send discovery ping to each other after cluster is formed?


I would like to confirm one thing about ZenDiscovery pinging.

Assuming there is single cluster including nodes a,b,c, once the cluster is formed, do all the nodes do zen discovery pinging to each other?

My understanding is below.

a -> b
a -> c
b -> a
b -> c
c -> a
c -> b

Definitive guide seems to not clarify this part so I asked the question.

After the cluster is formed, each node will send periodic fault-detection pings to the master, and the master will send periodic fault-detection pings to each node that has joined it. Otherwise, the nodes do not ping each other.


Thank you for the reply. I now clearly understand.

You're welcome.
