      Description

      When we run our Distributed system Model Checking (DMCK) in ZooKeeper v3.5.3
      by following the workload in ZK-2778:

      • initially start 2 ZooKeeper nodes
      • start 3 new nodes and let them join the cluster
      • do a reconfiguration where the newly joined will be PARTICIPANTS,
        while the previous 2 nodes change to be OBSERVERS

      We think our DMCK found this following bug:

      • one of the newly joined node crashes due to
        it receives an unexpected PROPOSAL message
        from the new leader in the cluster.

      For complete information of the bug, please see the document that is attached.
