scala - akka cluster seed nodes give error: dropping message for non-local recipient -

i'm trying create basic akka cluster on win 7 machine documentation:
http://doc.akka.io/docs/akka/snapshot/scala/cluster-usage.html

and i'm getting error when run seed nodes (more on them below)

adriansclustersystem-akka.actor.default-dispa tcher-16] [akka://adriansclustersystem/system/endpointmanager/reliableendpointwr iter-akka.tcp%3a%2f%2fadriansclustersystem%40127.0.0.1%3a2552-3/endpointwriter] dropping message [class akka.actor.selectchildname] non-local recipient [act or[akka.tcp://clustersystem@127.0.0.1:2552/]] arriving @ [akka.tcp://clustersys tem@127.0.0.1:2552] inbound addresses [akka.tcp://adriansclustersystem@127.0 .0.1:2552]

question: why getting error? did miss akka documentation?

my .conf file:
added line *to file listed @ url above * enabled-transports = ["akka.remote.netty.tcp"]

akka {   actor {     provider = "akka.cluster.clusteractorrefprovider"   }   remote {     enabled-transports = ["akka.remote.netty.tcp"]  <--added remoting     log-remote-lifecycle-events = off     netty.tcp {       hostname = "127.0.0.1"       port = 0     }   }   cluster {     seed-nodes = [     "akka.tcp://clustersystem@127.0.0.1:2551",     "akka.tcp://clustersystem@127.0.0.1:2552"]    auto-down = on   } } 

i start 2 nodes, each in different sbt windows

run-main sample.cluster.simple.simpleclusterapp 2551   run-main sample.cluster.simple.simpleclusterapp 2552 

both of these start fine repeatedly show error message:

if

run-main sample.cluster.simple.simpleclusterapp 

which supposed choose random port , run seed node on, starts of other 2 seed nodes, shows class not found exception info , no current members

yup hangs there , have close sbt window terminate it.

it looks seed nodes using clustersystem actor system name according logs using adriansclustersystem actor system name. try changing seed nodes to:

seed-nodes = [ "akka.tcp://adriansclustersystem@127.0.0.1:2551", "akka.tcp://adriansclustersystem@127.0.0.1:2552"]
