Use case description,
We have akka cluster A and akka cluster B. Our deathwatch actor is part of cluster A and another actor that we want to watch is part of cluster B. We are able to send actor msgs across clusters. But death watching across clusters is not happening. We enabled logs as well and found out that no heartbeat msgs are being sent. We have following scenarios for death watching in our application, out of which scenario 3 (death watching across clusters) is not working for us.
Scenario 1 : Deathwatch actor (in Cluster A) watches other actors in cluster A (WORKING)
Scenario 2 : Deathwatch actor (in Cluster A) watches other remote actors which are not part of any cluster (WORKING) using akka.remote.use-unsafe-remote-features-outside-cluster = on
Scenario 3 : Deathwatch actor (in Cluster A) watched other actor in cluster B (NOT WORKING)
Essentially we are looking for scenario 3. Is there a way to get this working?
p.s. - We are using akka 2.6.4
