Timeout Exception from RAFT

[Cheng Li]

Hi all,

I experienced the following exception when I issued a sequence of requests to a customized counter service (single-thread):

java.util.concurrent.TimeoutException

        at java.util.concurrent.CompletableFuture.timedAwaitDone(CompletableFuture.java:365)

        at java.util.concurrent.CompletableFuture.get(CompletableFuture.java:2260)

        at org.jgroups.protocols.raft.REDIRECT.set(REDIRECT.java:61)

        at org.jgroups.raft.RaftHandle.set(RaftHandle.java:73)

        at org.mpi.vasco.coordination.protocols.centr.rsm.CounterService.invoke(CounterService.java:219)

        at org.mpi.vasco.coordination.protocols.centr.rsm.CounterService.getAndAdd(CounterService.java:79)

I basically followed what Bela suggested, namely lowering resend_interval from 2000 to 100. However it didn't completely solve this problem. 

Can anybody help me?

Thanks,

   Cheng

Have you tried using the latest jgroups-raft from master? Lowering
resend_interval was just a workaround, but the fix was actually
implemented in [1] (in master).
