I downloaded the akka-sample-cluster-scala example from https://developer.lightbend.com/start/?group=akka&project=akka-samples-cluster-scala. Issued the sbt "runMain sample.cluster.simple.App" command per the readme file. It

  • printed lots of logs, but the line "Member is Up: akka://[email protected]:25251" appears 8 times (which after reading the source code is more or less what I expected)
  • waited for more stuff to happen

I changed sbt.version=1.5.6 to sbt.version=1.6.2 in build.properties to match other projects I have. I then reran the above command.

  • The "Member is Up" log message now appears only once.
  • It is soon followed by "Running CoordinatedShutdown with reason [JvmExitReason]"
  • Later, I find "[outbound connection to [akka://[email protected]:25251], message stream] Upstream failed, cause: StreamTcpException: The connection has been aborted"
  • The entire process stops.

Output from the first (working) run, below, followed by the output from the second run.

Pointers on how to use more recent versions of SBT would be appreciated.

Thanks!
Byron
