Hi all, I'm having a cluster system with many Master and many Slaves. I let Masters watch over Slaves and Slaves watch over their Master. So that when a Master is "terminated", corresponding slaves will re-register to a new Master and deny all jobs until a master is found . Or when a slave is "terminated", Master will get the jobs that were sent to that Slave and send it to other available slaves.
Currently i'm testing the high-availability of the cluster. When i turn off the JVM of Workers or Masters, Terminated messages are generated immediately, but if i try to turn off the network adapter and turn it on right about 10 or 20 seconds later to simulate network lagging, Terminated messages are not thrown immediately,usually a moment before MemberDown is thrown. And when i turn the adapter back on, things went back to normal, but the data that was sent when network was down is lost. i tried to catch DeadLetter and send them back to Master, but there is a case where Terminated was receive by Slave but Master never caught any. So my HA flow was ruined.( this is because as i said above, Slave will deny all messages until a Master is found, to prevent the slave from trying to send the message back to a dead actor forever, and Master never detected any Terminated messages, so the jobs that were deny by Slave were never recovered) So there are two things i'm concerned about: -is there a config so that when an unreachable message is thrown, the actor that is watch will be considered Terminated? -And the case where Master watch over slave and slave watches over Master but only 1 of them received Terminated message for the other? Thank you very much for your help, Best Regards Bourne. -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: >>>>>>>>>> http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
