@mac01021 my use case is somehow similar. My node are spawn on random machines so I have no clues about their host or available port.
The solution for now is a known, external application. future nodes connects to a server, give their host/port. after a while, the application notice the nodes of the collection of host/port. Starting from there I can build my cluster and remove the external temporary server. Did not find any other way though

(the Atomix cluster is on top of hadoop/yarn, which dynamically allow containers to run the nodes, and the external application is a akka-http server on the application master)

Sorry I was traveling all last week and I’m traveling again this week but then I’m staying home for a while :-)
But my travels bring Atomix bug fixes :-P

what would be the cause of io.atomix.copycat.session.ClosedSessionException: session closed
at io.atomix.copycat.client.session.ClientSession.submit(
at io.atomix.copycat.client.DefaultCopycatClient.submit(
at io.atomix.AtomixReplica$CombinedCopycatClient.submit(
at io.atomix.manager.resource.internal.InstanceClient.submit(

at io.atomix.collections.DistributedMap.keySet(
at com.salesforce.automation.precheckin.server.container.AtomixContainer.getIds(
what could be the cause of closed session exceptions, I see these randomly occurring during the course of my distributed cluster running
and whats the resolution for it? for now I am restarting the server , but would be problematic in production if this happens frequently
and sometimes the nodes infinitely keep trying to connect to each other. Even though there isnt any network partitioning

and then again

2018-03-13 23:04:22,466 INFO catalyst-event-loop-3 NettyClient:98 - Connected to
this just happens infinitely
