This is already possible with JMX
Currently if n is the number of seed nodes there will be n ping requests received by each of them for the partitioned node. (n*n) pings sent to that node, in all. Not a big deal in small clusters.
It is possible that the serialized cluster state, although it is compressed, could exceed akka.remote.netty.tcp.maximum-frame-size
which defaults to 128k.
Hi, first of all thank you for this project. While studying it I encountered this piece of code in QuorumLossAbdicator.scala:
def abdicate: Actor.Receive = {
case Abdicate =>
killSeq.foreach(context.stop)
SubmitClusterStateUpdate(clusterService, "eskka-quorum-loss-abdicator", Priority.URGENT, runOnlyOnMaster = false, abdicationClusterState) onComplete {
case Success(_) =>
log.debug("cleared cluster state, now invoking restart hook")
restartHook()
case Failure(e) =>
log.error(e, "failed to clear cluster state, will retry in {}", CheckInterval)
context.system.scheduler.scheduleOnce(CheckInterval, self, Abdicate)
}
}
In the failure handler you are accessing the actor context within the onComplete callback that, If i'm not wrong, could be run in a separate thread than the actor one. One solution could be to pipe the future back to the actor and do the handling there. Feel free to correct me if I missed some piece.
maybe do whatever zen does
I'm considering eskka in a small cluster, but I'ld love for support for SRV records or multiple A records against a single domain name entry to drive populating the seed nodes.
remote actors master<->follower exchange DiscoveryNode
with java ser
this leads to cross-version incompatibility
Having read http://aphyr.com/posts/317-call-me-maybe-elasticsearch and seeing your comment, it seems like it would be better to use eskka instead of ZenDisco.
Would you consider eskka ready for production use?
This would require overriding Akka's remoting Transport
