In general I'd advise not to update major versions of any software partially across a cluster. There's all sorts of implications in version compatibility and semantics. What are your hard requirements? Update the major on all software, deploy fresh, then do a "failover" to the new cluster, so if anything goes wrong, you can always switch back. > > On Wednesday, January 29, 2014 2:29:22 PM UTC-8, √ wrote: > >> Akka is not binary compatible between major releases. >> >> Cheers, >> V >> On Jan 29, 2014 11:10 PM, <[email protected]> wrote: >> >>> When running a cluster with a mix of 2.3.0-RC1 and 2.2.3 nodes, the >>> heartbeats fail because of the movement of the HeartBeat class. >>> >>> The class Heartbeat was moved from akka.cluster. >>> ClusterHeartbeatReceiver$Heartbeat to akka.cluster. >>> ClusterHeartbeatSender$Heartbeat.
