With akka-cluster 2.3.11 I seem to be able to have configuration below work as well, contrary to the claim here ( https://groups.google.com/forum/#!searchin/akka-user/seed$20node/akka-user/Wehd8AcN1pw/Tc0PYBq2DQAJ) that it doesn't work.
Node 1: akka.remote.netty.tcp.hostname = 127.0.0.1 akka.remote.netty.tcp.port = 2551 akka.cluster.seed-nodes = ["akka.tcp://[email protected]:2551 ", "akka.tcp://[email protected]:2552"] Node 2: akka.remote.netty.tcp.hostname = 127.0.0.1 akka.remote.netty.tcp.port = 2552 akka.cluster.seed-nodes = ["akka.tcp://[email protected]:255 <http://[email protected]:2551/>2", "akka.tcp:// [email protected]:255 <http://[email protected]:2552/>1"] Is it a fluke? The reason I tried this because I thought if it works it may be more flexible in cases where I don't want to run first seed node which in Patrick's configuration would prevent cluster from initializing. So, if you list all known nodes in seed nodes and first one is always the running node (rather weird) this may allow to start any number of nodes in any order and always guarantee cluster is initialized. Am I missing something here? Thanks, Andre Piwoni On Sunday, June 29, 2014 at 11:05:45 AM UTC-7, Patrik Nordwall wrote: > > I'm not sure I understand your problem.
