For the next person with this problem, the resolution is that if you even
run with one node you have to either configure seed nodes, manually or
programmatically join the cluster for the sharding system to work. My error
was not specifying the host name exactly in my remoting settings and
matching that. Also the actor system name must match exactly, in my case
playFramework 2.5 used the name "application". Here is the relevant parts
of the fixed config.
akka {
actor {
provider = "akka.cluster.ClusterActorRefProvider"
}
# See
http://doc.akka.io/docs/akka/snapshot/general/configuration.html#config-akka-remote
remote {
log-remote-lifecycle-events = off
enabled-transports = ["akka.remote.netty.tcp"]
netty.tcp {
hostname = 127.0.0.1
port = 2551
}
}
cluster {
# Configuration of seed nodes. Note that this must match the
akka.remote.netty settings EXACTLY for the node
# to join with or it won't work correctly.
seed-nodes = [
"akka.tcp://[email protected]:2551"
"akka.tcp://[email protected]:2552"
]
}
}
